Subset a codelist to only those codes from a particular domain.

Usage

subsetOnDomain(x, cdm, domain, negate = FALSE)

Arguments

x: A codelist.
cdm: A cdm reference via CDMConnector.
domain: Character vector with one or more of the OMOP CDM domains. The results will be restricted to the given domains. Check the available ones by running getDomains(). If NULL, all supported domains are included: Condition, Drug, Procedure, Device, Observation, and Measurement.
negate: If FALSE, only concepts with the domain specified will be returned. If TRUE, concepts with the domain specified will be excluded.

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).
