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)
