The contents of a generated `*-packages.json` file will be used to
create a package derivation for each R package listed in the file.
Some packages require overrides to specify external dependencies or other

`pkgs/development/r-modules/default.nix` file. As the `*-packages.nix`
`pkgs/development/r-modules/default.nix` file. As the `*-packages.json`
contents are automatically generated it should not be edited and broken
builds should be addressed using overrides.
