As discussed in #10623, many R modules fail to build on Darwin without the libraries and compilers provided by these packages. For more detail, please see comment: https://github.com/NixOS/nixpkgs/pull/10623#issuecomment-172375342
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/.nixpkgs/config.nix file:
{
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.
Updating the package set
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
Rscript generate-r-packages.R irkernel > irkernel-packages.nix.new
mv irkernel-packages.nix.new irkernel-packages.nix
generate-r-packages.R <repo> reads <repo>-packages.nix, therefor the renaming.
Testing if the Nix-expression could be evaluated
nix-build test-evaluation.nix --dry-run
If this exits fine, the expression is ok. If not, you have to edit default.nix
