A short post on my current set-up for R with nixpkgs and emacs to auto-compile my system configuration. Background This is my third post on working with nixpkgs and R. Part I covered ways of working effectively with R and nixpkgs Part II dealt with composing dependent devtools packages in a per-package environment, with a focus on rethinking and tidybayes.rethinking This final part is about automating the system-wide configuration using emacs.
