Get ATC properties from WHOCC website

Gets data from the WHO to determine properties of an ATC (e.g. an antibiotic) like name, defined daily dose (DDD) or standard unit.

This function requires an internet connection.

atc_online_property(
  atc_code,
  property,
  administration = "O",
  url = "https://www.whocc.no/atc_ddd_index/?code=%s&showdescription=no"
)

atc_online_groups(atc_code, ...)

atc_online_ddd(atc_code, ...)

Arguments

atc_code	a character or character vector with ATC code(s) of antibiotic(s)
property	property of an ATC code. Valid values are "ATC", "Name", "DDD", "U" ("unit"), "Adm.R", "Note" and groups. For this last option, all hierarchical groups of an ATC code will be returned, see Examples.
administration	type of administration when using property = "Adm.R", see Details
url	url of website of the WHO. The sign %s can be used as a placeholder for ATC codes.
...	parameters to pass on to atc_property

Questioning lifecycle

The lifecycle of this function is questioning. We are no longer convinced that this function is the optimal approach (but we do not know yet what a better approach would be), or whether this function should be in our AMR package at all.

On our website https://msberends.gitlab.io/AMR you can find a comprehensive tutorial about how to conduct AMR analysis, the complete documentation of all functions (which reads a lot easier than here in R) and an example analysis using WHONET data.

# \donttest{
