Usage

## S3 method for class 'myClimList'
x[...]

Arguments

Value

myClim object with subset of localities see myClim-package

Examples

filtered_data <- mc_data_example_raw[1:2]

Description

Function return number of localities.

Usage

## S3 method for class 'myClimList'
length(x, ...)

Arguments

Examples

length(mc_data_example_agg)

Description

mc_agg has two basic uses:

• aggregate (upscale) time step of microclimatic records with specified function (e. g. 15 min records to daily mean);

• convert myClim object from Raw-format to Agg-format see myClim-package without time-series modification, this behavior appears when fun=NULL, period=NULL.

Usage

mc_agg(
  data,
  fun = NULL,
  period = NULL,
  use_utc = TRUE,
  percentiles = NULL,
  min_coverage = 1,
  custom_start = NULL,
  custom_end = NULL,
  custom_functions = NULL
)

Arguments

Details

Any output of mc_agg is in Agg-format. That means the hierarchical level of logger is removed (Locality<-Logger<-Sensor<-Record), and all microclimatic records within the sensors are on the level of locality (Locality<-Sensor<-Record). See myClim-package.

In case mc_agg() is used only for conversion from Raw-format to Agg-format (⁠fun=NULL, period=NULL⁠) then microclimatic records are not modified. Equal step in all sensors is required for conversion from Raw-format to Agg-format, otherwise period must be specified.

When fun and period are specified, microclimatic records are aggregated based on a selected function into a specified period. The name of the aggregated variable will contain also the name of the function used for the aggregation (e.g. TMS_T1_mean). Aggregated time step is named after the first time step of selected period i.e. day = c(2022-12-29 00:00, 2022-12-30 00:00...); week = c(2022-12-19 00:00, 2022-12-28 00:00...); month = c(2022-11-01 00:00, 2022-12-01 00:00...); year = c(2021-01-01 00:00, 2022-01-01 00:00...). When first or last period is incomplete in original data, the incomplete part is extended with NA values to match specified period. For example, when you want to aggregate time-series to monthly mean, but your time-series starts on January 15 ending December 20, myClim will extend the time-series to start on January 1 and end on December 31. If you want to still use the data from the aggregation periods with not complete data coverage, you can adjust the parameter min_coverage.

Empty sensors with no records are excluded. mc_agg() return NA for empty vector except from fun=count which returns 0. When aggregation functions are provided as vector or list e.g. c(mean, min, max), than they are all applied to all the sensors and multiple results are returned from each sensors. When named list (names are the sensor ids) of functions is provided then mc_agg() apply specific functions to the specific sensors based on the named list list(TMS_T1=c("max", "min"), TMS_T2="mean"). mc_agg returns new sensors on the localities putting aggregation function in its name (TMS_T1 -> TMS_T1_max), despite sensor names contains aggregation function, sensor_id stays the same as before aggregation in sensor metadata (e.g. TMS_T1 -> TMS_T1). Sensors created with functions min, max, mean, percentile, sum, range keeps identical sensor_id and value_type as original input sensors. When function sum is applied on logical sensor (e.g. snow as TRUE, FALSE) the output is integer i.e. number of TRUE values.

Sensors created with functions count has sensor_id count and value_type integer, function coverage has sensor_id coverage and value_type real

If the myClim object contains any states (tags) table, such as error tags or quality tags, the datetime defining the start and end of the tag will be rounded according to the aggregation period parameter.

Value

Returns new myClim object in Agg-format see myClim-package When fun=NULL, period=NULL records are not modified but only converted to Agg-format. When fun and period are provided then time step is aggregated based on function.

Examples

hour_data <- mc_agg(mc_data_example_clean, c("min", "max", "percentile"),
                              "hour", percentiles = 50, min_coverage=0.5)
day_data <- mc_agg(mc_data_example_clean, list(TMS_T1=c("max", "min"), TMS_T2="mean"),
                             "day", min_coverage=1)
month_data <- mc_agg(mc_data_example_clean, fun=list(TMS_T3="below5"),period = "month",
                               custom_functions = list(below5=function(x){length(x[x<(-5)])}))

Description

This function creates a new virtual sensor on locality within the myClim data object. The virtual sensor represents the cumulative sum of the values on the input sensor. Names of new sensors are original sensor name + outpus_suffix.

Usage

mc_calc_cumsum(data, sensors, output_suffix = "_cumsum", localities = NULL)

Arguments

Details

If value type of sensor is logical, then output type is integer. (TRUE, TRUE, FALSE -> 2)

Value

The same myClim object as input but with added cumsum sensors.

Examples

cumsum_data <- mc_calc_cumsum(mc_data_example_agg, c("TMS_T1", "TMS_T2"))

Description

This function creates a new virtual sensor on locality within the myClim data object. The new virtual sensor provides FDD Freezing Degree Days.

Usage

mc_calc_fdd(data, sensor, output_prefix = "FDD", t_base = 0, localities = NULL)

Arguments

Details

The allowed step length for FDD calculation is day and shorter. Function creates a new virtual sensor with the same time step as input data. For shorter time steps than the day (which is however not intuitive for FDD) the FDD value is the contribution of the time step to the freezing degree day. Be careful while aggregating freezing degree days to longer periods only meaningful aggregation function is sum, but myClim allows you to apply anything see mc_agg().

Note that FDD is always positive number, despite summing freezing events. When you set t_base=-1 you get the sum of degree days below -1 °C but expressed in positive number if you set t_base=1 you get also positive number. Therefore pay attention to name of output variable which contains t_base value. FDD1_TMS_T3, t_base=1 vs FDDminus1_TMS_T3, t_base=-1

Value

The same myClim object as input but with added virtual FDD sensor

Examples

fdd_data <- mc_calc_fdd(mc_data_example_agg, "TMS_T3", localities = c("A2E32", "A6W79"))
fdd_agg <- mc_agg(fdd_data, list(TMS_T3=c("min", "max"), FDD5="sum"), period="day")

Description

This function creates a new virtual sensor for each locality within myClim data object. The new virtual sensor provides values of GDD (Growing Degree Days) in degees Celsius for each time step in the original timeseries.

Usage

mc_calc_gdd(data, sensor, output_prefix = "GDD", t_base = 5, localities = NULL)

Arguments

Details

Function calculates growing degree days as follows: GDD = max(0;(T - Tbase)) . period(days) The maximum allowed time step length for GDD calculation is one day. Function creates a new virtual sensor with the same time step as input data. For shorter time steps than one day, the GDD value is the contribution of the interval to the growing degree day, assuming constant temperature over this period. Be careful while aggregating growing degree days to longer periods, because only meaningful aggregation function here is sum, but myClim let you apply any aggregation function see mc_agg().

Value

The same myClim object as input but with added virtual GDD sensor

Examples

gdd_data <- mc_calc_gdd(mc_data_example_agg, "TMS_T3", localities = c("A2E32", "A6W79"))
gdd_agg <- mc_agg(gdd_data, list(TMS_T3=c("min", "max"), GDD5="sum"), period="day")

Description

This function creates a new virtual sensor on locality within the myClim data object. Virtual sensor hosts values of snow cover presence/absence detected from temperature time-series.

Usage

mc_calc_snow(
  data,
  sensor,
  output_sensor = "snow",
  localities = NULL,
  range = 1,
  tmax = 1.25,
  days = 3
)

Arguments

Details

Function detects snow cover from temperature time-series. Temperature sensor is considered as covered by snow when the maximal temperature in the preceding or subsequent time-window (specified by days param) does not exceed specific tmax threshold value (default 1.25°C) and the temperature range remain below specified range threshold (default 1°C). This function rely on insulating effect of a of snow layer, significantly reducing diurnal temperature variation and restricting the maximal temperature near the ground close to freezing point. Temperature sensor near the ground (TMS_T2) is default choice for snow-cover detection from Tomst TMS loggers. Snow detection with default values accurately detects snow of depth > 15cm (unpublished data). For detection of thin snow, range parameter should be set to 3-4 °C. The function returns vector of snow cover (TRUE/FLASE) with same time-step as input data. To get number of days with snow cover and more snow summary characteristics use mc_calc_snow_agg after snow detection.

Value

myClim object with added virtual sensor 'snow' (logical) indicating snow presence/absence (TRUE/FALSE).

Examples

data <- mc_calc_snow(mc_data_example_agg, "TMS_T2", output_sensor="TMS_T2_snow",
                     localities = c("A2E32", "A6W79"))

Description

This function works with the virtual snow sensor of TRUE/FALSE which is the output of mc_calc_snow(). So, before calling mc_calc_snow_agg you need to calculate or import mc_read_ TRUE/FALSE snow sensor. mc_calc_snow_agg returns the summary table of snow sensor (e.g number of days with snow cover, first and last date of continual snow cover longer than input period). The snow summary is returned for whole date range provided. And is returned as new data.frame in contrast with other mc_calc functions returning virtual sensors.

Usage

mc_calc_snow_agg(
  data,
  snow_sensor = "snow",
  localities = NULL,
  period = 3,
  use_utc = FALSE
)

Arguments

Details

Primary designed for virtual snow sensor calculated by mc_calc_snow(), but accepts any sensor with TRUE/FLAST snow event detection. If snow_sensor on the locality is missing, then locality is skipped.

Value

Returns data.frame with columns:

• locality - locality id

• snow_days - number of days with snow cover

• first_day - first day with snow

• last_day - last day with snow

• first_day_period - first day of period with continual snow cover based on period parameter

• last_day_period - last day of period with continual snow cover based on period parameter

Examples

data <- mc_calc_snow(mc_data_example_agg, "TMS_T2", output_sensor="TMS_T2_snow",
                     localities = c("A2E32", "A6W79"))
mc_calc_snow_agg(data, "TMS_T2_snow")

Description

This function creates a new virtual sensor on locality within the myClim data object. The virtual sensor provides the values of the change in stem size converted from raw Tomst units to micrometers. Note that newer versions of Tomst Lolly software can directly convert raw Tomst units to micrometers.

Usage

mc_calc_tomst_dendro(
  data,
  dendro_sensor = mc_const_SENSOR_Dendro_raw,
  output_sensor = mc_const_SENSOR_dendro_l_um,
  localities = NULL
)

Arguments

Value

myClim object same as input but with added dendro_l_um sensor

Examples

agg_data <- mc_calc_tomst_dendro(mc_data_example_agg, localities="A1E05")

Description

This function creates a new virtual sensor on locality within the myClim data object. The virtual sensor represents the vapor pressure deficit (in kPa) calculated from temperature and relative air humidity.

Usage

  data,
  temp_sensor = "HOBO_T",
  rh_sensor = "HOBO_RH",
  output_sensor = "VPD",
  elevation = 0,
  metadata_elevation = TRUE,
  localities = NULL
)

Arguments

Description

This function creates a new virtual sensor on the locality within the myClim data object. Function converts the raw TMS soil moisture (scaled TDT signal) to volumetric water content (VWC).

Usage

mc_calc_vwc(
  data,
  moist_sensor = mc_const_SENSOR_TMS_moist,
  temp_sensor = mc_const_SENSOR_TMS_T1,
  output_sensor = "VWC_moisture",
  soiltype = "universal",
  localities = NULL,
  ref_t = mc_const_CALIB_MOIST_REF_T,
  acor_t = mc_const_CALIB_MOIST_ACOR_T,
  wcor_t = mc_const_CALIB_MOIST_WCOR_T,
  frozen2NA = TRUE
)

Arguments

Details

This function is suitable for TOMST TMS loggers measuring soil moisture in raw TMS units. The raw TMS units represents inverted and numerically rescaled (1-4095) electromagnetic signal from the moisture sensor working on Time Domain Transmission principle (Wild et al. 2019). For TMS4 logger, the typical raw TMS moisture values range from cca 115 units in dry air to cca 3635 units in distilled water - see mc_calib_moisture.

Raw TMS moisture values can be converted to the soil volumetric water content with calibration curves. The function provides several experimentally derived calibration curves which were developped at reference temperature. To account for the difference between reference and actual temperature, the function uses actual soil temperature values measured by TMS_T1 soil temperature sensor.

The default calibration curve is "universal", which was designed for mineral soils (see Kopecký et al. 2021). Specific calibration curves were developed for several soil types (see Wild et al. 2019) and the user can choose one of these or can define its own calibration - see mc_data_vwc_parameters

Currently available calibration curves are: sand, loamy sand A, loamy sand B, sandy loam A, sandy loam B, loam, silt loam, peat, water, universal, sand TMS1, loamy sand TMS1, silt loam TMS1. For details see mc_data_vwc_parameters.

It is also possible to define a new calibarion function with custom parameters a, b and c. These can be derived e.g. from TOMST TMS Calibr utility after entering custom ratio of clay, silt, sand.

Warning: TOMST TMS Calibr utility was developed for TMS3 series of TMS loggers, which have different range of raw soil moisture values than TMS4 series.

The function by default replace the moisture records in frozen soils with NA (param frozen2NA), because the TMS soil moisture sensor was not designed to measure in frozen soils and the returned values are thus not comparable with values from non-frozen soil.

Value

myClim object same as input but with added virtual VWC moisture sensor

Description

Specialized function for calibration of TOMST TMS moisture sensor. Function calculate correction parameters for individual logger (slope and intercept) from TMS moisture measurements in demineralized water and dry air.

Usage

mc_calib_moisture(
  raw_air,
  raw_water,
  t_air = 24,
  t_water = 24,
  ref_air = 114.534,
  ref_water = 3634.723,
  ref_t = mc_const_CALIB_MOIST_REF_T,
  acor_t = mc_const_CALIB_MOIST_ACOR_T,
  wcor_t = mc_const_CALIB_MOIST_WCOR_T
)

Arguments

Details

This function calculate calibration parameters cor_factor and cor_intercept accounting for individual differencies in TMS moisture sensor signal in air and in water against reference loggers which were used for estimation of parameters of soil VWC conversion curves. These parameters must be loaded into myClim object mc_prep_calib_load() prior to calling mc_calc_vwc(). Parameters for soils available in my_Clim were derived for TMS3 logger version, with slightly different typical air and water signal. Correction parameters for TMS4 loggers therefore can be expected in the range of values: cor_factor = (-150; -450) and cor_slope = (100, 450)

Value

list with correction factor and correction slope

HOBO data format is export format from software HOBOware of Onset company for HOBO U23 Pro v2 loggers (Temperature/RH). Format is very variable and can be adjusted by user in preferences of HOBOware. Strucuture of HOBO files format can be partly detected automatically from header of data. Format of date-time (date_format) must be set manually in myClim reading functions (mc_read_files(), mc_read_data()). Date and time separated in more columns is not supported in myClim reading. If time zone is not defined in header of HOBO txt or csv file and is not UTC, then tz_offset must be filled in while reading. UTF-8 encoding of HOBO file is required for reding to myClim.

Description

This class is used for parsing source TXT/CSV files downloaded from microclimatic loggers.

Details

myClim offers several pre-defined logger file data formats, such as TOMST TMS or HOBO. Users can also define custom readings for their own loggers. Pre-defined and custom loggers in myClim each have their own specific object of class ⁠mc_{logger}DataFormat⁠, which defines the parameters for handling logger files. The pre-defined logger definitions are stored in the R environment object ./data/mc_data_formats.rda.

Slots

skip

The number of rows to skip before the first row containing microclimatic records. For example, to skip the header (default 0).

separator

The column separator (default is a comma ",").

date_column

The index of the date column - required (default NA).

date_format

The format of the date (default NA).

For a description of the date_format parameter, see strptime(). If the format is in ISO8601 and the function vroom::vroom() automatically detects datetime values, the date_format parameter can be NA.

na_strings

Strings for representing NA values, e.g., "-100", "9999" (default "").

error_value

The value that represents an error of the sensor, e.g., 404, 9999 (default NA).

The error_value is replaced by NA, and intervals of errors are flagged in sensor$states (see myClim-package).

columns

A list with names and indexes of value columns - required (default list()).

Names come from names(mc_data_sensors). Names are defined as constants ⁠mc_const_SENSOR_*⁠. For example, if the third column is temperature, you can define it as columns[[mc_const_SENSOR_T_C]] <- 3. There are universal sensors for arbitrary value types: mc_const_SENSOR_real, mc_const_SENSOR_integer and mc_const_SENSOR_logical. Multiple columns with same sensor type can be defined as columns[[mc_const_SENSOR_real]] <- c(2, 3, 4). The names in this example will be real1, real2 and real3.

col_types

Parameter for vroom::vroom() (default NA).

To ensure the correct reading of values, you have the possibility to strictly define the types of columns.

filename_serial_number_pattern

A character pattern for detecting the serial number from the file name (default NA).

The regular expression with brackets around the serial number. For example, the pattern for old TOMST files is "data_(\\d+)_\\d+\\.csv$". If the value is NA, the name of the file is used as the serial number.

data_row_pattern

A character pattern for detecting the correct file format (default NA).

The regular expression. If data_row_pattern is NA, then the file format is not checked.

logger_type

The type of logger: TMS, TMS_L45, Thermo, Dendro, HOBO, ... (default NA).

tz_offset

The timezone offset in minutes from UTC - required (default NA).

If the value of the tz_offset parameter is 0, then datetime values are in UTC. If the time zone offset is defined in the value, e.g., "2020-10-06 09:00:00+0100", and date_format is "%Y-%m-%d %H:%M:%S%z", the value is automatically converted to UTC.

Description

The wrapper function returning 4 standardised and ecologically relevant myClim variables derived from soil moisture measurements. The mc_env_moist function needs time-series of volumetric water content (VWC) measurements as input. Therefore, non-VWC soil moisture measurements must be first converted to VWC. For TMS loggers see mc_calc_vwc()

Usage

mc_env_moist(
  data,
  period,
  use_utc = TRUE,
  custom_start = NULL,
  custom_end = NULL,
  min_coverage = 1
)

Arguments

Details

This function was designed for time-series of step shorter than one day and will not work with coarser data. In contrast with other myClim functions returning myClim objects, this wrapper function returns long table. Variables are named based on sensor name, height, and function e.g., (VWC.soil_0_15_cm.5p, VWC.soil_0_15_cm.mean)

Standardised myClim soil moisture variables:

• VWC.5p: Minimum soil moisture = 5th percentile of VWC values

• VWC.mean: Mean soil moisture = mean of VWC values

• VWC.95p: Maximum soil moisture = 95th percentile of VWC values

• VWC.sd: Standard deviation of VWC measurements

Value

table in long format with standardised myClim variables

Examples

data <- mc_prep_crop(mc_data_example_agg, lubridate::ymd_h("2020-11-01 00"),
                     lubridate::ymd_h("2021-02-01 00"), end_included = FALSE)
data <- mc_calc_vwc(data, localities=c("A2E32", "A6W79"))
mc_env_moist(data, "month")

Description

The wrapper function returning 7 standardised and ecologically relevant myClim variables derived from temperature measurements.

Usage

mc_env_temp(
  data,
  period,
  use_utc = TRUE,
  custom_start = NULL,
  custom_end = NULL,
  min_coverage = 1,
  gdd_t_base = 5,
  fdd_t_base = 0
)

Arguments

Details

This function was designed for time-series of step shorter than one day and will not work with coarser data. It automatically use all available sensors in myClim object and returns all possible variables based on sensor type and measurement height/depth. In contrast with other myClim functions returning myClim objects, this wrapper function returns long table. The mc_env_temp function first aggregates time-series to daily time-step and then aggregates to the final time-step set in period parameter. Because freezing and growing degree days are always aggregated with sum function, these two variables are not first aggregated to the daily time-steps. Variables are named based on sensor name, height, and function e.g., (T.air_15_cm.max95p, T.air_15_cm.drange)

Standardised myClim temperature variables:

• min5p: Minimum temperature = 5th percentile of daily minimum temperatures

• mean: Mean temperature = mean of daily mean temperatures

• max95p: Maximum temperature = 95th percentile of daily maximum temperatures

• drange: Temperature range = mean of daily temperature range (i.e., difference between daily minima and maxima)

• GDD5: Growing degree days = sum of growing degree days above defined base temperature (default 5°C) gdd_t_base

• FDD0: Freezing degree days = sum of freezing degree days bellow defined base temperature (default 0°C) fdd_t_base

• frostdays: Frost days = number of days with frost (daily minimum < 0°C) fdd_t_base

Value

table in long format with standardised myClim variables

Examples

data <- mc_prep_crop(mc_data_example_clean, lubridate::ymd_h("2020-11-01 00"),
                     lubridate::ymd_h("2021-02-01 00"), end_included = FALSE)
mc_env_temp(data, "month")

Description

The wrapper function returning 2 standardised and ecologically relevant myClim variables derived from vapor pressure deficit. The mc_env_vpd function needs time-series of vapor pressure deficit measurements as input. Therefore, VPD must be first calculated from temperature and air humidity measurements - see mc_calc_vpd()

Usage

mc_env_vpd(
  data,
  period,
  use_utc = TRUE,
  custom_start = NULL,
  custom_end = NULL,
  min_coverage = 1
)

Arguments

Details

This function was designed for time-series of step shorter than one day and will not work with coarser data. The mc_env_vpd function first aggregates time-series to daily time-step and then aggregates to the final time-step set in period parameter. In contrast with other myClim functions returning myClim objects, this wrapper function returns long table. Variables are named based on sensor name, height, and function e.g., (VPD.air_150_cm.mean, VPD.air_150_cm.max95p)

Standardised myClim vapor pressure deficit variables:

• VPD.mean: Mean vapor pressure deficit = mean of daily mean VPD

• VPD.max95p: Maximum vapor pressure deficit = 95th percentile of daily maximum VPD

Description

This function filter data by localities, logger types and sensors.

Usage

mc_filter(
  data,
  localities = NULL,
  sensors = NULL,
  reverse = FALSE,
  stop_if_empty = TRUE,
  logger_types = NULL
)

Arguments

Details

In default settings it returns the object containing input localities / logger types / sensors. When you provide vector of localities e.g. localities=c("A6W79", "A2E32") selected localities are filtered with all loggers / sensors on those localities. The same as When you provide vector of logger_types logger_types=c("TMS", "TMS_L45") selected loggers by type are filtered through all localities (logger_types criterion is applicable only for raw data format see myClim-package) and the sensors parameter sensors=c("TMS_T1", "TMS_T2"), selected sensors are filtered through all localities. When you combine localities, logger_types and sensors, then filtering return selected sensors in selected loggers on selected localities.

Parameter reverse = TRUE returns myClim object without listed localities, or logger types or sensors. Using reverse = TRUE is not allowed for combination of localities and logger types and sensors. It is allowed to use reverse only with single filter criterion either locality, logger type or sensor.

• reverse = TRUE and logger_types are selected then the listed logger types are removed from all localities.

• reverse = TRUE and localities are selected then the listed localities are removed from myClim object.

• reverse = TRUE and sensors are selected then listed sensors are removed from all loggers / localities.

Examples

mc_info_states(mc_data_example_raw)

Description

The function is designed to merge time-series data obtained through repeated downloads in the same location. Within a specific locality, the function performs the merging based on logger type, physical element, and sensor height

Usage

mc_join(data, comp_sensors = NULL)

Arguments

Details

Joining is restricted to the myClim Raw-format (refer to myClim-package). Loggers need to be organized within localities. The simplest method is to use mc_read_data, providing both files_table and localities_table. When using mc_read_files without metadata, a bit more coding is needed. In this case, you can create multiple myClim objects and specify correct locality names afterwards, then merge these objects using mc_prep_merge, which groups loggers based on identical locality names.

The joining function operates seamlessly without user intervention in two scenarios:

1. when the start of a newer time series aligns with the end of an older one, and

2. when the two time-series share identical values during the overlap.

However, if values differ during the overlap, the user is prompted to interactively choose which time-series to retain and which to discard. myClim provides information about differing time-series in the console, including locality ID, problematic interval (start-end), older logger ID and its time series start-end, and newer logger ID and its time series start-end. Additionally, an interactive graphical window (plotly) displays conflicting time series, allowing the user to zoom in and explore values. In case of multiple conflicts, myClim sequentially asks the user for decisions.

Users have seven options for handling overlap conflicts, six of which are pre-defined. The seventh option allows the user to specify the exact time to trim the older time-series and use the newer one. The options include:

• 1: using the older logger (to resolve this conflict),

• 2: using the newer logger (to resolve this conflict),

• 3: skip this join (same type loggers in locality aren't joined),

• 4: always using the older logger (to resolve this and all other conflicts),

• 5: always using the newer logger (to resolve this and all other conflicts)

• 6: exit joining process.

Users must press the number key, hit Return/Enter, or write in console the exact date in the format ⁠YYYY-MM-DD hh:mm⁠ to trim the older series and continue with the newer series.

Loggers with multiple sensors are joined based on one or more selected sensors (see parameter comp_sensors). The name of the resulting joined sensor is taken from the logger with the oldest data. If serial_number is not equal during logger joining, the resulting serial_number is NA. Clean info is changed to NA except for the step. When joining a non-calibrated sensor with a calibrated one, the calibration information must be empty in the non-calibrated sensor.

For example of joining see myClim vignette.

WARNING

mc_join expects a maximum of one logger of a certain type and height measuring certain elements in one locality. In other words, if you use multiple logger of identical type at identical heights in one locality, you cannot use mc_join directly; you have to split your locality into sub-localities.

Value

myClim object with joined loggers.

mc_data_physical

Description

Function plots single sensor form myClim data into PNG file with image() R base function. This was designed for fast, and easy data visualization especially focusing on missing values visualization and general data picture.

Usage

mc_plot_image(
  data,
  filename,
  title = "",
  localities = NULL,
  sensors = NULL,
  height = 1900,
  left_margin = 12,
  use_utc = TRUE
)

Arguments

Details

Be careful with bigger data. Can take some time.

Value

PNG file created as specified in output file name

Examples

tmp_dir <- tempdir()
tmp_file <- tempfile(tmpdir = tmp_dir)
mc_plot_image(mc_data_example_clean, tmp_file, "T1 sensor", sensors="TMS_T1")
file.remove(tmp_file)

Description

Function plots data with ggplot2 geom_line. Plot is returned as ggplot faced grid and is optimized for saving as facet, paginated PDF file.

Usage

mc_plot_line(
  data,
  filename = NULL,
  sensors = NULL,
  scale_coeff = NULL,
  png_width = 1900,
  png_height = 1900,
  start_crop = NULL,
  end_crop = NULL,
  use_utc = TRUE,
  localities = NULL,
  facet = "locality",
  color_by_logger = FALSE
)

Arguments

Details

Saving as the PDF file is recommended, because the plot is optimized to be paginate PDF (facet line plot is distributed to pages), each locality can be represented by separate plot (facet = "locality") default, which is especially useful for bigger data. When facet = NULL then single plot is returned showing all localities together. When facet = physical sensors with identical physical units are grouped together across localities. Maximal number of physical units (elements) of sensors to be plotted in one plot is two. First element is related to primary and second to secondary y axis. In case, there are multiple sensors with identical physical on one locality, they are plotted together for facet = "locality" e.g., when you have TMS_T1, TMS_T2, TMS_T3, Thermo_T, and VWC you get plot with 5 lines of different colors and two y axes. Secondary y axes are scaled with calculation values * scale_coeff. If scaling coefficient is NULL than function try to detects scale coefficient from physical unit of sensors see mc_Physical. Scaling is useful when plotting together e.g. temperature and moisture. For native myClim loggers (TOMST, HOBO U-23) scaling coefficients are pre-defined. For other cases when plotting two physicals together, it is better to set scaling coefficients by hand.

Value

ggplot2 object

Examples

tms.plot <- mc_filter(mc_data_example_agg, localities = "A6W79")
p <- mc_plot_line(tms.plot,sensors = c("TMS_T3","TMS_T1","TMS_moist"))
p <- p+ggplot2::scale_x_datetime(date_breaks = "1 week", date_labels = "%W")
p <- p+ggplot2::xlab("week")
p <- p+ggplot2::scale_color_manual(values=c("hotpink","pink", "darkblue"),name=NULL)

Description

Function save separate files (*.png) per the loggers to the directory. Only Raw-format supported, Agg-format not supported. For Agg-format use mc_plot_line(). Function was primary designed for Tomst TMS loggers for fast, and easy data visualization.

Usage

mc_plot_loggers(
  data,
  directory,
  localities = NULL,
  sensors = NULL,
  crop = c(NA, NA)
)

Arguments

Value

PNG files created in the output directory

Examples

tmp_dir <- file.path(tempdir(), "plot")
mc_plot_loggers(mc_data_example_clean, tmp_dir)
unlink(tmp_dir, recursive=TRUE)

Description

Function plots data with ggplot2 geom_raster. Plot is returned as ggplot faced raster and is primary designed to be saved as .pdf file (recommended) or .png file. Plotting into R environment without saving any file is also possible. See details.

Usage

mc_plot_raster(
  data,
  filename = NULL,
  sensors = NULL,
  by_hour = TRUE,
  png_width = 1900,
  png_height = 1900,
  viridis_color_map = NULL,
  start_crop = NULL,
  end_crop = NULL,
  use_utc = TRUE
)

Arguments

Details

Saving as the .pdf file is recommended, because the plot is optimized to be paginate PDF (facet raster plot is distributed to pages), which is especially useful for bigger data. In case of plotting multiple sensors to PDF, the facet grids are grouped by sensor. I.e., all localities of sensor_1 followed by all localities of sensor_2 etc. When plotting only few localities, but multiple sensors, each sensor has own page. I.e., when plotting data from one locality, and 3 sensors resulting PDF has 3 pages. In case of plotting PNG, sensors are plotted in separated images (PNG files) by physical. I.e, when plotting 3 sensors in PNG it will save 3 PNG files named after sensors. Be careful with bigger data in PNG. Play with png_height and png_width. When too small height/width, image does not fit and is plotted incorrectly. Plotting into R environment instead of saving PDF or PNG is possible, but is recommended only for low number of localities (e.g. up to 10), because high number of localities plotted in R environment results in very small picture which is hard/impossible to read.

Value

list of ggplot2 objects

Examples

tmp_dir <- tempdir()
tmp_file <- tempfile(tmpdir = tmp_dir, fileext=".pdf")
mc_plot_raster(mc_data_example_agg, filename=tmp_file, sensors=c("TMS_T3","TM_T"))
file.remove(tmp_file)

Description

This function calibrate values of sensor (microclimatic records) using the myClim object sensor$calibration parameters provided by mc_prep_calib_load(). Microclimatic records are changed and myClim object parameter sensor$metadata@calibrated is set to TRUE. It isn't allowed to calibrate sensor multiple times.

Usage

mc_prep_calib(data, localities = NULL, sensors = NULL)

Arguments

Details

This function performs calibration itself. It uses the calibration values (cor_factor, cor_slope) stored in myClim object sensor metadata sensor calibration loaded with mc_prep_calib_load(). As it is possible to have multiple calibration values for one sensor in time (re-calibration after some time) different calibration values can be applied based on the calibration time. Older microclimatic records then first calibration datetime available are calibrated anyway (in case sensor was calibrated ex-post) with the first calibration parameters available.

This function is not designed for moisture_raw calibration (conversion to volumetric water content) for this use mc_calc_vwc()

Only sensors with real value type can be calibrated. see mc_data_sensors()

Value

same myClim object as input but with calibrated sensor values.

Description

This function loads calibration parameters from data.frame logger_calib_table and stores them in the myClim object metadata. This function does not calibrate data. For calibration itself run mc_prep_calib()

Usage

mc_prep_calib_load(data, calib_table)

Arguments

Details

This function allows user to provide correction coefficients cor_factor and cor_slope for linear sensor calibration. Calibrated data have by default the form of linear function terms:

⁠calibrated value = original value * (cor_slope + 1) + cor_factor⁠

In case of one-point calibration, cor_factor can be estimated as: ⁠cor_factor = reference value - sensor value⁠ and cor_slope should be set to 0. This function loads sensor-specific calibration coefficients from calib_table and stores them into myClim Raw-format object metadata. The calib_table is data.frame with 5 columns:

• serial_number = serial number of the logger

• sensor_id = name of sensor, e.g. "TMS_T1"

• datetime = the date of the calibration in POSIXct type

• cor_factor = the correction factor

• cor_slope = the slope of calibration curve (in case of one-point calibration, use cor_slope = 0)

It is not possible to change calibration parameters for already calibrated sensor. This prevents repeated calibrations. Once mc_prep_calib() is called then it is not allowed to provide new calibration data, neither run calibration again.

Value

myClim object with loaded calibration information in metadata. Microclimatic records are not calibrated, only ready for calibration. To calibrate records run mc_prep_calib()

Description

By default, mc_prep_clean runs automatically when mc_read_files() or mc_read_data() are called. mc_prep_clean checks the time-series in the myClim object in Raw-format for missing, duplicated, and disordered records. The function can either directly regularize microclimatic time-series to a constant time-step, remove duplicated records, and fill missing values with NA (resolve_conflicts=TRUE); or it can insert new states (tags) see mc_states_insert to highlight records with conflicts i.e. duplicated datetime but different measurement values (resolve_conflicts=FALSE) but not perform the cleaning itself. When there were no conflicts, cleaning is performed in both cases (⁠resolve_conflicts=TRUE or FALSE⁠) See details.

Usage

mc_prep_clean(data, silent = FALSE, resolve_conflicts = TRUE)

Arguments

Details

The function mc_prep_clean can be used in two different ways depending on the parameter resolve_conflicts. When resolve_conflicts=TRUE, the function performs automatic cleaning and returns a cleaned myClim object. When resolve_conflicts=FALSE, and myClim object contains conflicts, the function returns the original, uncleaned object with tags (states) see mc_states_insert highlighting records with duplicated datetime but different measurement values. When there were no conflicts, cleaning is performed in both cases (⁠resolve_conflicts=TRUE OR FALSE⁠)

Processing the data with mc_prep_clean and resolving the conflicts is a mandatory step required for further data handling in the myClim library.

This function guarantee that all time series are in chronological order, have regular time-step and no duplicated records. Function mc_prep_clean use either time-step provided by user during data import with mc_read (used time-step is permanently stored in logger metadata mc_LoggerMetadata; or if time-step is not provided by the user (NA),than myClim automatically detects the time-step from input time series based on the last 100 records. In case of irregular time series, function returns warning and skip the series.

In case the time-step is regular, but is not nicely rounded, function rounds the time series to the closest nice time and shifts original data. E.g., original records in 10 min regular step c(11:58, 12:08, 12:18, 12:28) are shifted to newly generated nice sequence c(12:00, 12:10, 12:20, 12:30). Note that microclimatic records are not modified but only shifted. Maximum allowed shift of time series is 30 minutes. For example, when the time-step is 2h (e.g. 13:33, 15:33, 17:33), the measurement times are shifted to (13:30, 15:30, 17:30). When you have 2h time step and wish to go to the whole hour (13:33 -> 14:00, 15:33 -> 16:00) the only way is aggregation - use mc_agg(period="2 hours") command after data cleaning.

In cases when the user provides a time-step during data import in mc_read functions instead of relying on automatic step detection, and the provided step does not correspond with the actual records (i.e., the logger records data every 900 seconds but the user provides a step of 3600 seconds), the myClim rounding routine consolidates multiple records into an identical datetime. The resulting value corresponds to the one closest to the provided step (i.e., in an original series like ...9:50, 10:05, 10:20, 10:35, 10:50, 11:05..., the new record would be 10:00, and the value will be taken from the original record at 10:05). This process generates numerous warnings in resolve_conflicts=TRUE and a multitude of tags in resolve_conflicts=FALSE.

Value

• cleaned myClim object in Raw-format (default) resolve_conflicts=TRUE or resolve_conflicts=FALSE but no conflicts exist

• cleaning log is by default printed in console, but can be called also later by mc_info_clean()

• non cleaned myClim object in Raw-format with "conflict" tags resolve_conflicts=FALSE and conflicts exist

Examples

cleaned_data <- mc_prep_clean(mc_data_example_raw)

Description

This function crop data by datetime

Usage

mc_prep_crop(
  data,
  start = NULL,
  end = NULL,
  localities = NULL,
  end_included = TRUE
)

Arguments

Details

Function is able to crop data from start to end but works also with start only and end only. When only start is provided, then function crops only the beginning of the tim-series and vice versa with end.

If start or end is a single POSIXct value, it is used for all or selected localities (regular crop). However, if start and end are vectors of POSIXct values with the same length as the localities vector, each locality is cropped by its own time window (irregular crop).

The end_included parameter is used for selecting, whether to return data which contains end time or not. For example when cropping the data to rounded days, typically users use midnight. 2023-06-15 00:00:00 UTC. But midnight is the last date of ending day and the same time first date of the next day. Thus, there will be the last day with single record. This can be confusing in aggregation (e.g. daily mean of single record per day, typically NA) so sometimes it is better to exclude end and crop on 2023-06-14 23:45:00 UTC (15 minutes records).

Value

cropped data in the same myClim format as input.

Examples

cropped_data <- mc_prep_crop(mc_data_example_clean, end=as.POSIXct("2020-02-01", tz="UTC"))

Description

This function approximate NA (missing) values. It was designed to fill only small gaps in microclimatic time-series therefore, the default maximum length of the gap is 5 missing records and longer gaps are not filled Only linear method is implemented from zoo::na.approx function.

Usage

mc_prep_fillNA(
  data,
  localities = NULL,
  sensors = NULL,
  maxgap = 5,
  method = "linear"
)

Arguments

Value

myClim object with filled NA values

Description

This function is designed to merge more existing myClim objects into one.

Usage

mc_prep_merge(data_items)

Arguments

Details

This function works only when the input myClim objects have the same format (Raw-format, Agg-format) It is not possible to merge Raw wit Agg format. Identical time-step is required for Agg-format data.

When the merged myClim objects in Raw-format contains locality with same names (locality_id), than list of loggers are merged on the locality. Sensors with the same name does not matter here. Loggers with the same name within the locality are allowed in the Raw-format.

When the merged myClim objects in Agg-format contains locality with same names (locality_id). than the sensors are merged on the locality. Sensors with same names are renamed.

Value

merged myClim object in the same format as input objects

Examples

merged_data <- mc_prep_merge(list(mc_data_example_raw, mc_data_example_raw))

Description

This function allows you to add or modify locality metadata including locality names. See mc_LocalityMetadata. You can import metadata from named list or from data frame. See details.

Usage

mc_prep_meta_locality(data, values, param_name = NULL)

Arguments

Details

Locality metadata is critical e.g. for correctly handling time zones. By providing geographic coordinates in locality metadata, the user can later harmonize all data to the local solar time (midday) #' with mc_prep_solar_tz() or calculate temporal offset to the UTC base on local time-zone. Alternatively, the user can directly provide the offset (in minutes) for individual localities. This can be useful especially for heterogeneous data sets containing various localities with loggers recording in local time. By providing temporal offset for #' each locality separately, you can unify the whole dataset to UTC. Note that when tz_offset is set manually, than tz_type is set to ⁠user defined⁠.

For minor metadata modification it is practical to use named list in combination with param_name specification. E.g. when you wish to modify only time zone offset, then set param_name="tz_offset" and provide named list with locality name and offset value list(A1E05=60). Similarly, you can modify other metadata slots mc_LocalityMetadata.

For batch or generally more complex metadata modification you can provide data.frame with columns specifying locality_id and one of ⁠new_locality_id, elevation, lat_wgs84, lon_wgs84, tz_offset⁠. Provide locality_id (name) and the value in column of metadata you wish to update. In case of using data.frame use param_name = NULL

Value

myClim object in the same format as input, with updated metadata

Examples

data <- mc_prep_meta_locality(mc_data_example_raw, list(A1E05=60), param_name="tz_offset")

Description

This function allows you to modify sensor metadata including sensor name. See mc_SensorMetadata

Usage

mc_prep_meta_sensor(
  data,
  values,
  param_name,
  localities = NULL,
  logger_types = NULL
)

Arguments

Value

myClim object in the same format as input, with updated sensor metadata

Examples

data <- mc_prep_meta_sensor(mc_data_example_raw, list(TMS_T1="my_TMS_T1"), param_name="name")

Description

This function calculates the temporal offset between local solar time and UTC time zone. Calculation is based on geographic coordinates of each locality. Therefore, the function does not work when longitude coordinate is not provided.

Usage

mc_prep_solar_tz(data)

Arguments

Details

myClim assumes that the data are in UTC. To calculate temporal offset based on local solar time, this function requires geographic coordinates (at least longitude) to be provided in locality metadata slot lon_wgs84 (in decimal degrees). Geographic coordinates for each locality can be provided already during data reading, see mc_read_data(), or added later with mc_prep_meta_locality() function.

TZ offset (in minutes) is calculated as longitude / 180 * 12 * 60.

Value

myClim object in the same format as input, with tz_offset filled in locality metadata

Examples

data_solar <- mc_prep_solar_tz(mc_data_example_clean)

Description

This function creates new virtual sensor labelling anomalies in TMS logger caused by displacement out of from soil.

Usage

mc_prep_TMSoffsoil(
  data,
  localities = NULL,
  soil_sensor = mc_const_SENSOR_TMS_T1,
  air_sensor = mc_const_SENSOR_TMS_T2,
  moist_sensor = mc_const_SENSOR_TMS_moist,
  output_sensor = "off_soil",
  smooth = FALSE,
  smooth_window = 10,
  smooth_threshold = 0.5,
  sd_threshold = 0.76085,
  minmoist_threshold = 721.5
)

Arguments

Details

TMS loggers, when correctly installed in the soil, exhibit certain temperature and soil moisture signal characteristics. Temperature varies the most at the soil interface, and temperature fluctuations in the soil are minimized. The moisture signal from a sensor that has lost direct contact with the soil is reduced. The following criteria are used for detecting faulty measurements: the ratio of the standard deviations of the soil sensor to the above-ground sensor within 24h moving window is greater than the defined threshold (default 0.76085), and simultaneously, the soil moisture minimum within 24h mowing window is less than 721.5. Optionally, the prediction results can be smoothed using a floating window to average-out unlikely short periods detected by the algorithm. Selection and parametrization of criteria was done using a recursive partitioning (rpart::rpart) on the training set of 7.8M readings in 154 TMS timeseries from different environmental settings (temperate forests, tropical rainforest, cold desert, alpine and subnival zone, and invalid measurements from loggers stored in the office or displaced from the soil). Sensitivity of the method (true positive rate) on was 95.1% and specificity (true negative rate) was 99.4% using function default parameters. Smoothing with 10 day floating window increased sensitivity to 96.8% while retaining specifity at the same level of 99.4%. Decreasing 'smooth_threshold' below 0.5 will extend periods flagged as faulty measurement.

Value

numeric vector (0 = correct measurement, 1 = faulty measurement) stored as virtual sensor in myClim object

Examples

data <- mc_read_files(system.file("extdata", "data_93142760_201904.csv", package = "myClim"),
                      "TOMST")
data <- mc_prep_TMSoffsoil(data)
mc_plot_line(data, sensors = c("off_soil","TMS_T1", "TMS_T2","TMS_T3"))

Description

This function has two tables as the parameters.

(i) files_table is required parameter, it ust contain paths pointing to raw csv logger files, specification of data format (logger type) and locality name.

(ii) localities_table is optional, containing locality id and metadata e.g. longitude, latitude, elevation...

Usage

mc_read_data(
  files_table,
  localities_table = NULL,
  clean = TRUE,
  silent = FALSE,
  user_data_formats = NULL
)

Arguments

Details

The input tables could be R data.frames or csv files. When loading files_table and localities_table from external CSV they must have header, column separator must be comma ",". If you only need to place loggers to correct localities, files_table is enough. If you wish to provide localities additional metadata, you need also localities_table

By default, data are cleaned with the function mc_prep_clean see function description. mc_prep_clean detects gaps in time-series data, duplicated records, or records in the wrong order. Importantly, mc_prep_clean also applies a step parameter if provided. The step parameter can be used either instead of automatic step detection which can sometime failed, or to prune microclimatic data. For example, if you have a 15-minute time series but you wish to keep only one record per hour (without aggregating), you can use step parameter. However, if a step is provided and clean = FALSE, then the step is only stored in the metadata of myClim, and the time-series data is not cleaned, and the step is not applied.

Value

myClim object in Raw-format see myClim-package

See Also

mc_DataFormat

Examples

files_csv <- system.file("extdata", "files_table.csv", package = "myClim")
localities_csv <- system.file("extdata", "localities_table.csv", package = "myClim")
tomst_data <- mc_read_data(files_csv, localities_csv)

Description

This function read one or more CSV/TXT files or directories of identical, pre-defined logger type (format) see mc_DataFormat and mc_data_formats. This function does not support loading locality or sensor metadata while reading. Metadata can be loaded through mc_read_data() or can be provided later with function mc_prep_meta_locality()

Usage

mc_read_files(
  paths,
  dataformat_name,
  logger_type = NA_character_,
  recursive = TRUE,
  date_format = NA_character_,
  tz_offset = NA_integer_,
  step = NA_integer_,
  clean = TRUE,
  silent = FALSE,
  user_data_formats = NULL
)

Arguments

Details

If file is not in expected format, then file is skipped and warning printed in console. CSV/TXT files (loggers raw data) are in resulting myClim object placed to separate localities with empty metadata. Localities are named after serial_number of logger. Pre-defined logger types are ("Dendro","HOBO","Thermo","TMS","TMS_L45")

By default, data are cleaned with the function mc_prep_clean see function description. mc_prep_clean detects gaps in time-series data, duplicated records, or records in the wrong order. Importantly, mc_prep_clean also applies a step parameter if provided. The step parameter can be used either instead of automatic step detection which can sometime failed, or to prune microclimatic data. For example, if you have a 15-minute time series but you wish to keep only one record per hour (without aggregating), you can use step parameter. However, if a step is provided and clean = FALSE, then the step is only stored in the metadata of myClim, and the time-series data is not cleaned, and the step is not applied.

It is good to specify date_formatas this can often be the reason why reading have failed (see warnings after reading).

Description

This function removes states (tags) defined by locality ID, sensor name, or tag value, or any combination of these three.

Usage

mc_states_delete(data, localities = NULL, sensors = NULL, tags = NULL)

Arguments

Value

myClim object in the same format as input, with deleted sensor states

Examples

data <- mc_states_delete(mc_data_example_clean, localities="A1E05",
                         sensors=c(mc_const_SENSOR_Dendro_T, mc_const_SENSOR_Dendro_raw))

Description

This function creates a new state from an existing logical (TRUE/FALSE) sensor and assigns this new state to selected existing sensors.

Usage

mc_states_from_sensor(
  data,
  source_sensor,
  tag,
  to_sensor,
  value = NA,
  inverse = FALSE
)

Arguments

Details

The function is applicable only for logical (TRUE/FALSE) sensors. It allows you to convert such sensors into a state, represented as a tag. For example, you might calculate the estimation of snow cover using mc_calc_snow (TRUE/FALSE) and then want to remove temperature records when the logger was covered by snow. In this case, you can convert the snow sensor to a state, and then replace the values with NA for that state using mc_states_replace. In opposite case when you wish to keep e.g. only the moisture records when sensor was covered by snow, use inverse = TRUE.

Value

Returns a myClim object in the same format as the input, with added states.

Examples

data <- mc_calc_snow(mc_data_example_agg, "TMS_T2", output_sensor="snow")
data <- mc_states_from_sensor(data, source_sensor="snow", tag="snow", to_sensor="TMS_T2")

Description

This function inserts new states (tags) into the selected part of the sensor time-series. For more information about the structure of states (tags), see myClim-package. mc_states_insert() does not affect existing rows in the states (tags) table but only inserts new rows even if the new ones are identical with existing (resulting in duplicated states).

Usage

mc_states_insert(data, states_table)

Arguments

Details

As a template for inserting states (tags), it is recommended to use the output of mc_info_states(), which will return the table with all necessary columns correctly named. The sensor_name and value columns are optional and do not need to be filled in.

When locality_id is provided but sensor_name is NA in the states (tags) table, states are inserted for all sensors within the locality.

The states (tags) are associated with the sensor time-series, specifically to the defined part of the time-series identified by start and end date times. A single time series can contain multiple states (tags) of identical or different types, and these states (tags) can overlap. Start and end date times are adjusted to fit within the range of logger/locality datetime and are rounded according to the logger's step. For instance, if a user attempts to insert a tag beyond the sensor time-series range, mc_states_insert will adjust the start and end times to fit the available measurements. If a user defines a start time as '2020-01-01 10:23:00' on a logger with a 15-minute step, it will be rounded to '2020-01-01 10:30:00'.

Value

myClim object in the same format as input, with inserted sensor states

Examples

states <- data.frame(locality_id="A1E05", logger_index=1, sensor_name="Thermo_T", tag="error",
                     start=lubridate::ymd_hm("2020-10-28 9:00"),
                     end=lubridate::ymd_hm("2020-10-28 9:30"))
data <- mc_states_insert(mc_data_example_clean, states)

Description

This function creates a state (tag) for all values that are either above or below certain thresholds (min_value, max_value), or at break points where consecutive values of microclimate time-series suddenly jump down or up (positive_jump, negative_jump).

Usage

mc_states_outlier(
  data,
  table,
  period = NULL,
  range_tag = "range",
  jump_tag = "jump"
)

Arguments

Details

The best way to use this function is to first generate a table (data.frame) with pre-defined minimum, maximum, and jump thresholds using the mc_info_range function. Then modify the thresholds as needed and apply the function (see example). All values above max_value and below min_value are tagged by default with the range tag. When consecutive values suddenly decrease by more than negative_jump or increase by more than positive_jump, such break points are tagged with the jump tag. It is possible to use only the range case, only the jump case, or both.

When the period parameter is used, the jump values are modified; range values are not affected. Depending on the logger step, the value of jump is multiplied or divided. For example, when the loggers are recording with a step of 15 minutes (900 s) and the user sets period = "1 hour" together with positive_jump = 10, then consecutive values differing by (10 * (15 / 60) = 2.5) would be tagged. In this example, but with recording step 2 hours (7200 s), consecutive values differing by (10 * (120 / 60) = 20) would be tagged.

Value

Returns a myClim object in the same format as the input, with added states.

Examples

range_table <- mc_info_range(mc_data_example_clean)
range_table$negative_jump[range_table$sensor_name == "TMS_moist"] <- 500
data <- mc_states_outlier(mc_data_example_clean, range_table)

Description

This function replace values of sensors by states with tag.

Usage

mc_states_replace(data, tags, replace_value = NA)

Arguments

Value

myClim object in the same format as input, with replaced values

Examples

states <- data.frame(locality_id="A1E05", logger_index=1, sensor_name="Thermo_T", tag="error",
                     start=lubridate::ymd_hm("2020-10-28 9:00"),
                     end=lubridate::ymd_hm("2020-10-28 9:30"))
data <- mc_states_insert(mc_data_example_clean, states)
data <- mc_states_replace(data, "error")

Description

This function creates a logical (TRUE/FALSE) sensor from specified states.

Usage

mc_states_to_sensor(
  data,
  tag,
  to_sensor,
  source_sensor = NULL,
  inverse = FALSE
)

Arguments

 If `to_sensor` is a single sensor name, the logical sensor is created 
 from the union of states across all sensors with the same tag. If `to_sensor` 
 contains multiple sensor names, the length of the vector must match the length 
 of `source_sensor`.

Details

The function allows you to create a TRUE/FALSE sensor based on a tag. By default, it generates a new sensor by combining all tags specified in the tag parameter from all available sensors at a particular logger or locality. If you specify a source_sensor, the function converts only the tags from that specific sensor. You can also create multiple new sensors from multiple tags by specifying more values in to_sensor and providing exactly the same number of corresponding values in source_sensor. For example, you can create one TRUE/FALSE sensor from states on a temperature sensor and another from tags on a moisture sensor.

If you use parameter inverse = TRUE you get FALSE for each record where tag is assigned to and FALSE for the records where tag is absent. By default you get TRUE for all the records where tag is assigned.

Value

Returns a myClim object in the same format as the input, with added sensors.

Examples

states <- data.frame(locality_id="A1E05", logger_index=1, sensor_name="Thermo_T", tag="error",
                     start=lubridate::ymd_hm("2020-10-28 9:00"),
                     end=lubridate::ymd_hm("2020-10-28 9:30"))
data <- mc_states_insert(mc_data_example_clean, states)
data <- mc_states_to_sensor(data, tag="error", to_sensor="error_sensor")

Description

This function updates (replaces) existing states (tags). For more information about the structure of states (tags), see myClim-package. In contrast with mc_states_insert, which does not affect existing states (tags), mc_states_update deletes all old states and replaces them with new ones, even if the new states table contains fewer states than original object.

Usage

mc_states_update(data, states_table)

Arguments

Details

As a template for updating states (tags), it is recommended to use the output of mc_info_states(), which will return the table with all necessary columns correctly named. The sensor_name and value columns are optional and do not need to be filled in.

The states (tags) are associated with the sensor time-series, specifically to the defined part of the time-series identified by start and end date times. A single time series can contain multiple states (tags) of identical or different types, and these states (tags) can overlap. Start and end date times are adjusted to fit within the range of logger/locality datetime and are rounded according to the logger's step. For instance, if a user attempts to insert a tag beyond the sensor time-series range, mc_states_insert will adjust the start and end times to fit the available measurements. If a user defines a start time as '2020-01-01 10:23:00' on a logger with a 15-minute step, it will be rounded to '2020-01-01 10:30:00'.

In contrast with mc_states_insert, the automatic filling of states when locality_id is provided but sensor_name is NA is not implemented in mc_states_update. When a user needs to update states (tags) for all sensors within the locality, each state (tag) needs to have a separate row in the input table.

Value

myClim object in the same format as input, with updated sensor states

Examples

states <- mc_info_states(mc_data_example_clean)
states$value <- basename(states$value)
data <- mc_states_update(mc_data_example_clean, states)
