Description

getDescendants

Usage

getDescendants(
  cdm,
  conceptId,
  withAncestor = FALSE,
  ingredientRange = c(0, Inf),
  doseForm = NULL
)

Arguments

cdm	cdm_reference via CDMConnector
conceptId	concpet_id to search
withAncestor	If TRUE, return column with ancestor. In case of multiple ancestors, concepts will be separated by ";"
ingredientRange	Used to restrict descendant codes to those associated with a specific number of drug ingredients. Must be a vector of length two with the first element the minimum number of ingredients allowed and the second the maximum. A value of c(2, 2) would restrict to only concepts associated with two ingredients.
doseForm	Only descendants codes with the specified drug dose form will be returned. If NULL, descendant codes will be returned regardless of dose form.

Value

The descendants of a given concept id

Examples

cdm <- mockVocabRef()
getDescendants(cdm = cdm, conceptId = 1)
