exitAtObservationEnd()
resets cohort end date based on a set of specified
column dates. The last date that occurs is chosen.
This functions changes cohort end date to the end date of the observation period corresponding to the cohort entry. In the case were this generates overlapping records in the cohort, overlapping entries will be merged.

cohort,
cohortId = NULL,
limitToCurrentPeriod = TRUE,
name = tableName(cohort),
.softValidation = FALSE
)
cohort |
A cohort table in a cdm reference. |
cohortId |
Vector identifying which cohorts to modify (cohort_definition_id or cohort_name). If NULL, all cohorts will be used; otherwise, only the specified cohorts will be modified, and the rest will remain unchanged. |
limitToCurrentPeriod |
If TRUE, limits the cohort to one entry per person, ending at the current observation period. If FALSE, subsequent observation periods will create new cohort entries. |
name |
Name of the new cohort table created in the cdm object. |
.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 |
The cohort table.
