Package 'CBRT'

Title: CBRT Data on Turkish Economy
Description: The Central Bank of the Republic of Turkey (CBRT) provides one of the most comprehensive time series databases on the Turkish economy. The 'CBRT' package provides functions for accessing the CBRT's electronic data delivery system <https://evds2.tcmb.gov.tr/>. It contains the lists of all data categories and data groups for searching the available variables (data series). As of November 3, 2024, there were 40,826 variables in the dataset. The lists of data categories and data groups can be updated by the user at any time. A specific variable, a group of variables, or all variables in a data group can be downloaded at different frequencies using a variety of aggregation methods.

Information about data categories

Description

Creates a meta data object for all categories

Usage

getAllCategoriesInfo(CBRTKey = myCBRTKey)

Arguments

CBRTKey

Your personal CBRT access key

Value

a data.table object

Examples

## Not run: 
allCBRTCategories <- getAllCategoriesInfo()

## End(Not run)

Information about data groups

Description

Creates a meta data object for all data gorups

Usage

getAllGroupsInfo(CBRTKey = myCBRTKey)

Arguments

CBRTKey

Your personal CBRT access key

Value

a data.table object

Examples

## Not run: 
allCBRTGroups <- getAllGroupsInfo()

## End(Not run)

Information about data series

Description

Creates a meta data object for all data series

Usage

getAllSeriesInfo(CBRTKey = myCBRTKey, verbose = TRUE)

Arguments

CBRTKey

Your personal CBRT access key
verbose

TRUE turns on status and information messages to the console

Value

a data.table object

Examples

## Not run: 
allCBRTSeries <- getAllSeriesInfo()

## End(Not run)

Downloading data groups

Description

Downloads all data series of a data group

Usage

getDataGroup(
  group,
  CBRTKey = myCBRTKey,
  freq,
  startDate = "01-01-1950",
  endDate,
  na.rm = TRUE,
  verbose = TRUE
)

Arguments

group

Code for the data group.
CBRTKey

Your personal CBRT access key.
freq

Numeric, the frequency of the data series. If not defined, the default (the highest possible frequency) will be used. The frequencies are as follows:

1

Day

2

Work day

3

Week

4

Biweekly

5

Month
