Oct 2020: EDM Data Dictionary and Release Notes

Flatiron R Packages

We’ve released a new version (0.2.0) of our cohort selection R package, rwdplyr, that includes:

• Updates to the summarize_patient_biomarker_status to align with the recent guidance released in the related tutorial, including new select methods and arguments
• Warnings in derive_age_at_event if a negative age is calculated
• Helper functions count_rows and count_patients for sizing remote and local tables
• New summarize_and_apply_gap_rule to calculate patient activity and filter patients in a single function call
• More detail can be found in the release notes in the repository

If you do not have access to rwdplyr and would like to, please submit the form on this webpage and Flatiron will follow up with further information.
