R

Install R, package compilation dependencies, and a practical user-level package set for data analysis, teaching, and research.

ansible-playbook -i inventory -K playbooks/lab-stack.yml --tags r

The r role installs R without installing RStudio Desktop. It also installs the Fedora system and build libraries needed to compile common spatial R packages such as sf, terra, s2, units, and leaflet. The role creates ~/R/library, records that location as R_LIBS_USER in the Ansible-managed block of ~/.Renviron, and installs the configured CRAN packages there.

Use project environments

Use renv in each project to record and restore exact package versions. The shared user library supplies useful starting packages, but it does not replace a project lockfile.

renv::init()
renv::snapshot()
renv::restore()

If installation reports a package lock, close R, Rscript, RStudio, and rsession, then rerun the role. The role never kills these processes. It removes stale 00LOCK* directories only when none of them is running, and installs only configured top-level packages that are missing.

✅ Check

R --version
Rscript -e 'cat(Sys.getenv("R_LIBS_USER"), "\n")'
Rscript -e 'library(tidyverse); library(renv); sessionInfo()'
