## Updating the package set {#updating-the-package-set}

There is a script and associated environment for regenerating the package
100
+
sets and synchronising the rPackages tree to the current CRAN and matching
101
+
BIOC release. These scripts are found in the `pkgs/development/r-modules`
102
+
directory and executed as follows:
103
+

104
```bash
100

nix-shell generate-shell.nix

`generate-r-packages.R <repo>` reads `<repo>-packages.nix`, therefor the renaming.

If this exits fine, the expression is ok. If not, you have to edit `default.nix`
123
+
Some packages require overrides to specify external dependencies or other
124
+
patches and special requirements. These overrides are specified in the
125
+
`pkgs/development/r-modules/default.nix` file. As the `*-packages.nix`
126
+
contents are automatically generated it should not be edited and broken
127
+
builds should be addressed using overrides.
