subsetCohorts(
  cohort,
  cohortId,
  name = tableName(cohort),
  .softValidation = TRUE
)

Value

Cohort table with only cohorts in cohortId.

Arguments

cohort

A cohort table in a cdm reference.

cohortId

Vector identifying which cohorts to include (cohort_definition_id or cohort_name). Cohorts not included will be removed from the cohort set.

.softValidation

Whether to perform a soft validation of consistency. If set to FALSE four additional checks will be performed: 1) a check that cohort end date is not before cohort start date, 2) a check that there are no missing values in required columns, 3) a check that cohort duration is all within observation period, and 4) that there are no overlapping cohort entries

cdm$cohort1 |> subsetCohorts(cohortId = 1)
# }
