How to add R packages to nix install of HaskellR?

[skeydan]

Hi,

I'm new to nix (but have to use it to get HaskellR running, as I'm on Fedora and running into the linker problem described in the FAQ), and I wonder how to add R packages (ggplot2, etc...) to the installation?

Thank you very much in advance, Sigrid

Hi.

The simplest way in the nix-based setup that I've found so far is modifying shell.nix locally.

Example:

diff --git a/shell.nix b/shell.nix
index 3c6f56d..58d3e3a 100644
--- a/shell.nix
+++ b/shell.nix
@@ -18,6 +18,8 @@ haskell.lib.buildStackProject {
       python35Packages.ipython
       python35Packages.jupyter_client
       python35Packages.notebook
+      rPackages.ggplot2
+      rPackages.rjson
       R
       zeromq
       zlib

You can use other packages in the same way. This way they will be accessible using H, inline-r, of if you build standalone changes.

Would it work for you?

This works like a charm, thank you so much!
