R-CMD-check Codecov test coverage Lifecycle: experimental

The CDISC Analysis Results Standard aims to facilitate automation, reproducibility, reusability, and traceability of analysis results data (ARD). The {cards} package creates these CDISC Analysis Result Data Sets.

Use cases:

  1. Quality Control (QC) of existing tables and figures.

  2. Pre-calculate statistics to be summarized in tables and figures.

  3. Medical writers may easily access statistics and place in reports without copying and pasting from reports.

  4. Provides a consistent format for results and lends results to be combined across studies for re-use and re-analysis.

The {cards} package exports three types of functions:

  1. Functions to create basic ARD objects.

  2. Utilities to create new ARD objects.

  3. Functions to work with existing ARD objects.

The {cardx} R package is an extension to {cards} that uses the utilities from {cards} and exports functions for creating additional ARD objects––including functions to summarize t-tests, Wilcoxon Rank-Sum tests, regression models, and more.
