Subset a codelist to only those with a particular route category

Description

Subset a codelist to only those with a particular route category

Usage

subsetOnRouteCategory(x, cdm, routeCategory, negate = FALSE)

Arguments

x	A codelist.
cdm	A cdm reference to an OMOP CDM dataset. If data is held within a database, the vocabulary tables should be in the same schema as the clinical tables (person, observation period, and so on).
routeCategory	Only codes with the specified route will be returned. If NULL, descendant codes will be returned regardless of route category. Use getRoutes() to find the available route categories.
negate	If FALSE, only concepts with the routeCategory specified will be returned. If TRUE, concepts with the routeCategory specified will be excluded.

Value

The codelist with only those concepts associated with the specified route categories (if negate is FALSE) or the codelist without those concepts associated with the specified route categories (if negate is TRUE).

Examples

library(CodelistGenerator)
library(omopgenerics)
cdm <- mockVocabRef()
codes <- subsetOnRouteCategory(
              x = newCodelist(list("codes" = c(20,21))),
              cdm = cdm,
              routeCategory = "topical")
codes
