Description

Given a cohort expression, this function extracts the concept set expressions from cohort definition expression.

Usage

Arguments

cohortExpression

A R-object (list) that represents cohort definition expression. This is derived from cohort expression json using RJSONIO::fromJSON(content = json, digits = 23). Note: it is important to use digits = 23, otherwise numerical precision may be lost for large integer values like conceptId's in cohort definition. The cohort expression JSON is commonly generated using OHDSI tools like Atlas or CapR.

Value
