-R packages
-==========
-
-## Installation
-
-Define an environment for R that contains all the libraries that you'd like to
-use by adding the following snippet to your $HOME/.config/nixpkgs/config.nix file:
-
-```nix
-{
-    packageOverrides = super: let self = super.pkgs; in
-    {
-
-        rEnv = super.rWrapper.override {
-            packages = with self.rPackages; [
-                devtools
-                ggplot2
-                reshape2
-                yaml
-                optparse
-                ];
-        };
-    };
-}
-```
-
-Then you can use `nix-env -f "<nixpkgs>" -iA rEnv` to install it into your user
-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.
-
-## RStudio
-
-RStudio uses a standard set of packages and ignores any custom R
-environments or installed packages you may have.  To create a custom
-environment, see `rstudioWrapper`, which functions similarly to
-`rWrapper`:
-
-```nix
-{
-    packageOverrides = super: let self = super.pkgs; in
-    {
-
-        rstudioEnv = super.rstudioWrapper.override {
-            packages = with self.rPackages; [
-                dplyr
-                ggplot2
-                reshape2
-                ];
-        };
-    };
-}
-```
-
-Then like above, `nix-env -f "<nixpkgs>" -iA rstudioEnv` will install
-this into your user profile.
-
-Alternatively, you can create a self-contained `shell.nix` without the need to
-modify any configuration files:
-
-```nix
-{ pkgs ? import <nixpkgs> {}
-}:
-
-pkgs.rstudioWrapper.override {
-  packages = with pkgs.rPackages; [ dplyr ggplot2 reshape2 ];
-}
-
-```
-
-Executing `nix-shell` will then drop you into an environment equivalent to the
-one above. If you need additional packages just add them to the list and
-re-enter the shell.
-
-## Updating the package set
-
-```bash
-nix-shell generate-shell.nix
-
-Rscript generate-r-packages.R cran  > cran-packages.nix.new
-mv cran-packages.nix.new cran-packages.nix
-
-Rscript generate-r-packages.R bioc  > bioc-packages.nix.new
-mv bioc-packages.nix.new bioc-packages.nix
-```
-
-`generate-r-packages.R <repo>` reads  `<repo>-packages.nix`, therefor the renaming.
-
-
-## Testing if the Nix-expression could be evaluated
-
-```bash
-nix-build test-evaluation.nix --dry-run
-```
-
-If this exits fine, the expression is ok. If not, you have to edit `default.nix`
