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.

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`

Options for parameter administration:

"Implant" = Implant

"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.

Examples

if (FALSE) {
# oral DDD (Defined Daily Dose) of amoxicillin
atc_online_property("J01CA04", "DDD", "O")
# parenteral DDD (Defined Daily Dose) of amoxicillin
atc_online_property("J01CA04", "DDD", "P")

atc_online_property("J01CA04", property = "groups") # search hierarchical groups of amoxicillin
# [1] "ANTIINFECTIVES FOR SYSTEMIC USE"
# [2] "ANTIBACTERIALS FOR SYSTEMIC USE"
# [3] "BETA-LACTAM ANTIBACTERIALS, PENICILLINS"
# [4] "Penicillins with extended spectrum"
