createSubsetCohortWindow: Create a relative time window for cohort subset operations

In CohortGenerator: Cohort Generation for the OMOP Common Data Model

Create a relative time window for cohort subset operations

Description

This function is used to create a relative time window for cohort subset operations. The cohort window allows you to define an interval of time relative to the target cohort's start/end date and the subset cohort's start/end date.

Usage

createSubsetCohortWindow(
  startDay,
  endDay,
  targetAnchor,
  subsetAnchor = NULL,
  negate = FALSE
)

Arguments

startDay	The start day for the time window
endDay	The end day for the time window
targetAnchor	To anchor using the target cohort's start date or end date. The parameter is specified as 'cohortStart' or 'cohortEnd'.
subsetAnchor	To anchor using the subset cohort's start date or end date. The parameter is specified as 'cohortStart' or 'cohortEnd'.
negate	Allows for negating a window, a way to detect that a subset does not occur relative to a target

Value

a SubsetCohortWindow instance
