This workshop gives system administrators and platform engineers an end-to-end view of installing, configuring, and maintaining shared R environments. Topics include R and Rscript, site-wide configuration files, library locations, and how .libPaths() determines package discovery. Participants examine CRAN, Bioconductor, and internal repositories before moving to package dependency types and system dependencies. The session covers tools such as pak and r-system-rules, building a local repository, checking a package cohort before release, and installing or updating packages predictably. Discussion of production issues connects these mechanisms with the ongoing work of supporting a dependable organizational R environment.
