Overview

About

Maintained by Malan BosmanFirst published 2025-02-109 releasesCRAN page ↗GitHub ↗

Analysis Results Standard (ARS), a foundational standard by CDISC (Clinical Data Interchange Standards Consortium), provides a logical data model for metadata describing all components to calculate Analysis Results. https://www.cdisc.org/standards/foundational/analysis-results-standard Using 'siera', ARS metadata is ingested (JSON or Excel format), producing R programmes to generate Analysis Results Datasets (ARDs). Supports arbitrary-depth table structures, multi-value conditions, data-driven groupings, and CDISC-compliant ARD column stamping.
