Create cohort template to union multiple cohorts

This is a union between all cohorts within a specified set of ids. If an individual has multiple overlapping eras, they will be merged into a single time window.

Distinct eras will be mapped to the same cohort id but remain distinct. For example:

“` A: [——–] B: [–] C: [——-] “` Becomes: “` A U B U C: [————–] “`

And “` A: [——–] B: [——-] “` Becomes “` A U B: [——–] [——-] “` It is never allowed to have multiple overlapping eras for the same individual within a cohort

Usage

createUnionCohortTemplate(cohortIds, cohortName, unionCohortId)

Arguments

cohortIds

A vector of `cohort_definition_id` values for the input cohorts.

cohortName

The Name of the resulting cohort

unionCohortId

The `cohort_definition_id` for the resulting union cohort.
