To create a DHIS2 connection, you need a DHIS2 base URL, username, password, and an API version The R6 Class called 'Dhis2r' representing a DHIS2 instance connection
An R6 class called Dhis2r.
You can use a DHIS2 instance connection to get data several times without needing to manually supply your user credentials on each API call.
request_sentThe request used to perform an API call
nameName of the user
access_rightsThe access rights the user has on the DHIS2 instance
account_infoInformation of the logged account credentials
new()
Create a connection to a DHIS2 instance using basic authentication
Dhis2r$new(
base_url,
username = NULL,
password = NULL,
api_token = NULL,
api_version = NULL,
api_version_position = c("after", "before")
)base_urlBase url e.g https://play.dhis2.org/
usernameRegistered username e.g "admin"
passwordRegistered password e.g "district"
api_tokenPersonal Access Token (PAT) to use instead of username and password
api_versionThe api version e.g "33"
api_version_positionposition where the api_version is after or before in web API url i.e /api/
A new 'Dhis2r' object
get_user_info()
Get information of the logged in user
Dhis2r$get_user_info()
A vector
get_metadata()
Get metadata about any available resource from a DHIS2 instance e.g "dataElements", "organisationUnits", "indicators", "periodTypes"
Dhis2r$get_metadata(endpoint = NULL, fields = c("name", "id"))endpointa resource, get the available resources using 'get_metadata()' without any arguments
fieldsThe specific columns to be return in the dataframe e.g c("name","id")
A data frame
get_metadata_fields()
Get all possible fields for a specific metadata resource from a DHIS2 instance
Dhis2r$get_metadata_fields(endpoint)
endpointa resource, get the available resources using 'get_metadata()' without any arguments
A vector of all possible fields for a specific metadata
get_analytics()
Get all possible analytics resources from a DHIS2 instance i.e
Dhis2r$get_analytics(
analytic,
org_unit,
period,
output_scheme = c("UID", "NAME")
)analyticvector of ID of specific analytic(s) from a DHIS2 instance
org_unitvector of ID of specific organisation unit(s) from a DHIS2 instance
periodvector of relative or fixed periods from a DHIS2 instance
output_schemeOutput type ID or Names of fields
A data frame of the analytics resource
get_any_analytic()
Get all any analytics resource from a DHIS2 instance to cater for long DHIS2 favorites
Dhis2r$get_any_analytic(endpoint_url)
endpoint_urlstring part of Analytic(s) from a DHIS2 instance api endpoint starting from 'analytics.json?dimension='
A data frame of the analytics resource
clone()
The objects of this class are cloneable with this method.
Dhis2r$clone(deep = FALSE)
deepWhether to make a deep clone.

The relative periods are relative to the current date and allow e.g. for creating dynamic reports
data(relative_periods)data(relative_periods)
A data frame with 30 rows and 2 columns:
Period type
Relative period to be used
