Why does nix search not show any rPackages?

Help

Hey All,

My when I use nix search to find rPackages, I am not able to find anything using the following:

[user@localhost ~]$ nix search nixpkgs rPackages

* legacyPackages.x86_64-linux.flutterPackages.stable (3.3.8)

[user@localhost ~]$

However, on the NixOS website there are more than 10000 r packages available. Can anyone explain to me why this is the case and how I could see these packages using nix search ?

Thanks!

nix search nixpkgs#rPackages shows them, and you can search for specific ones with nix search nixpkgs#rPackages foo.

The rPackages subscope is apparently marked for nix search not to enter it. I believe haskellPackages is the same. Iā€™m not sure precisely why, though.
