Get RxClass relationship types

rxclass_relas() is a helper function that queries the RxClass API for generally valid relationships within the data. Note that just because a relationship is generally valid within a rela_source, not every drug or RxCUI will have a corresponding relationship asserted.

Usage

rxclass_relas(rela_source)

Arguments

rela_source

RxClass relationship source, such as "ATC", "DAILYMED", "FDASPL", "MEDRT", "SNOMEDCT", or "VA".

Value

A tibble of relationship names for the selected source.
