I wanted to install the previous version of R, so I used Nix Package Versions to find the command:
nix-shell -p R -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/824421b1796332ad1bcb35bc7855da832c43305f.tar.gz
It triggered the downloading of seemingly every recursive dependency and has been compiling them for the past couple hours (currently churning through glibc). Is this expected? There’s no way to install binary versions of old packages?
And does the situation change if I want to run a version of R that I had previously installed before updating my whole system?
