I have been meaning to reply to this for some time and maybe a partial answer now is better than a complete answer in several months time.
I use envrc https://github.com/purcell/envrc with direnv https://direnv.net/ and nix https://nixos.org/. With these I can have a different R (and different packages) in each project I work on and emacs and any shells automatically pick up this version and required libraries. Just to be clear I can have different versions of R in different projects. I can also have different versions of packages in different projects. And ESS just picks them up without me configuring emacs. For a project I am working on at the moment I have my R set up as > let > R-with-my-packages = nixpkgs.rWrapper.override{ > packages = with nixpkgs.rPackages; [ > ggplot2 > maps > rnaturalearth > rnaturalearthdata > sf > tidyverse > ]; }; And all the dependencies for the R packages are made available (e.g. gdal, proj, geos, libtiff) automatically. In this example, I didn’t specify versions and let nix choose them for me so I got e.g ggplot 3.4.2 but I could have specified a different version e.g. a bug fixed version that hasn’t been released to CRAN. Of course you can use this for much more than R. PS I want to say thanks to everyone that contributes to ESS and provides help on this email channel. It’s a great tool :-) Dominic Steinitz domi...@steinitz.org http://idontgetoutmuch.org Twitter: @idontgetoutmuch [[alternative HTML version deleted]] ______________________________________________ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
