Cohort definition Application Programming in R
Capr is an R package to develop and manipulate OHDSI cohort definitions. This package assists in creating a cohort definition that can be compiled by circe-be using CirceR. Cohort definitions developed in Capr are compatible with OHDSI ATLAS. Additionally the package allows for development of cohort design components, sub-items of a cohort design that are meant to be reusable and mutable to assist creating cohorts in study development.
Requires R (version 3.6.0 or higher). Installation on Windows requires RTools. Libraries used in Capr require Java. Capr requires a connection to an OMOP vocabulary database to query concepts.
