either of the cohorts.

cohort,
cohortId = NULL,
gap = 0,
cohortName = NULL,
keepOriginalCohorts = FALSE,
name = tableName(cohort),
.softValidation = TRUE
)

gap |
Number of days between two subsequent cohort entries to be merged in a single cohort record. |

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 cohort table.
