Add cohort subset definition to a cohort definition set

Given a subset definition and cohort definition set, this function returns a modified cohortDefinitionSet That contains cohorts that's have parent's contained within the base cohortDefinitionSet

Also adds the columns subsetParent and isSubset that denote if the cohort is a subset and what the parent definition is.

addCohortSubsetDefinition(
  cohortDefinitionSet,
  cohortSubsetDefintion,
  targetCohortIds = NULL,
  overwriteExisting = FALSE
)

Arguments

cohortDefinitionSet

data.frame that conforms to CohortDefinitionSet

cohortSubsetDefintion

CohortSubsetDefinition instance

targetCohortIds

Cohort ids to apply subset definition to. If not set, subset definition is applied to all base cohorts in set (i.e. those that are not defined by subsetOperators). Applying to cohorts that are already subsets is permitted, however, this should be done with care and identifiers must be specified manually

overwriteExisting

Overwrite existing subset definition of the same definitionId if present
