Get descendant codes for a given concept

Description

Get descendant codes for a given concept

Usage

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

Arguments

cdm	A cdm reference via CDMConnector.
conceptId	concept_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 codes with the specified dose form will be returned. If NULL, descendant codes will be returned regardless of dose form. Use 'getDoseForm()' to see the available dose forms.

Value

The descendants of a given concept id.

Examples

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