Subset a codelist to only those codes with a range of number of ingredients

Usage

subsetOnIngredientRange(x, cdm, ingredientRange, 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).
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.
negate: If FALSE, only concepts with the ingredient range specified will be returned (both limits included). If TRUE, concepts with number of ingredients outside the range will be returned.

Value

The codelist with only those concepts associated with the domain (if negate = FALSE) or the codelist without those concepts associated with the domain (if negate = TRUE).

              x = newCodelist(list("codes" = c(10L, 13L))),
              cdm = cdm,
              ingredientRange = c(2, 10))
