@ -29,6 +29,30 @@ profile. The set of available libraries can be discovered by running the
command `nix-env -f "<nixpkgs>" -qaP -A rPackages`. The first column from that
output is the name that has to be passed to rWrapper in the code snipped above.
However, if you'd like to add a file to your project source to make the
environment available for other contributors, you can create a `default.nix`
file like so:
```nix
let
pkgs = import <nixpkgs> {};
stdenv = pkgs.stdenv;
in with pkgs; {
myProject = stdenv.mkDerivation {
name = "myProject";
version = "1";
src = if pkgs.lib.inNixShell then null else nix;
buildInputs = with rPackages; [
R
ggplot2
knitr
];
};
}
```
and then run `nix-shell .` to be dropped into a shell with those packages
available.
