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

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 WHOCC. The sign %s can be used as a placeholder for ATC codes.

url_vet

url of website of the WHOCC for veterinary medicine. The sign %s can be used as a placeholder for ATC_vet codes (that all start with "Q").

Options for parameter administration:

  • "Implant" = Implant

  • "Inhal" = Inhalation

  • "Instill" = Instillation

  • "N" = nasal

  • "O" = oral

  • "P" = parenteral

  • "R" = rectal

  • `"mcg"`` = microgram

  • "U" = unit

  • "TU" = thousand units

  • "MU" = million units

  • "mmol" = millimole

  • "ml" = milliliter (e.g. eyedrops)

N.B. This function requires an internet connection and only works if the following packages are installed: curl, rvest, xml2.

Stable lifecycle


The lifecycle of this function is stable. In a stable function, major changes are unlikely. This means that the unlying code will generally evolve by adding new arguments; removing arguments or changing the meaning of existing arguments will be avoided.

If the unlying code needs breaking changes, they will occur gradually. For example, a parameter will be deprecated and first continue to work, but will emit an message informing you of the change. Next, typically after at least one newly released version on CRAN, the message will be transformed to an error.
