R-Guru Pharma

The pharmaceutical industy has quickly adapted to embrace R! The Pharmaverse concept is created as a collaboration amoung top pharma and industy organizatins for open-source solutions. Organizations now have the option to continue programming in R using common packages or use the packages from Pharmaverse to get a jump start. With Pharmaverse R package compliance standards, organizations can feel more confident to apply these packages. Smarter organizations make time to confirm packages behave as expected with expected results. Up to 50% of Pharmaverse is built using Tidyverse. This page is designed to help guide you using Pharmaverse packages.

Pharmaverse has R packages that work as modules to help in the CDISC submission process. Organizations can plan to understand and start to incoporate R packages as needed to grow. See new to clinical data and new to CDISC to learn about the basics. Note that the SDTMs and ADaMs pages within R-Guru utilize base R and other non-Pharmaverse packages.
