Copy a cohort table

Description

copyCohorts() copies an existing cohort table to a new location.

Usage

copyCohorts(cohort, name, n = 1, cohortId = NULL, .softValidation = TRUE)

Arguments

cohort	A cohort table in a cdm reference.
name	Name of the new cohort table created in the cdm object.
n	Number of times to duplicate the selected cohorts.
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

Value

A new cohort table containing cohorts from the original cohort table.
