R: Difference between revisions

You will need to obtain the `rev` and `sha256` for the package on github [https://search.nixos.org/packages?show=nix-prefetch-git&type=packages&query=nix-prefetch-git which can be found by using the `nix-prefetch-git` command line tool.] For the above example, running <code>nix-prefetch-git https://github.com/rstudio/rmarkdown</code> from a terminal will generate the information. You may need to manually specify other R-package/system dependencies for the specific package in the `propagatedBuildInputs`. This information can be found in the `DESCRIPTION` file of the R-package source directory.

== Install an R package from source ==

If you need a specific version of a package or find one that is not available in Nixpkgs, you can use `rPackages.buildRPackage` to build from source. The example below builds S4Arrays from BioConductor.<syntaxhighlight lang="nix">

let

pkgs = import <nixpkgs> { };

customPackage = pkgs.rPackages.buildRPackage {

name = "S4Arrays";

src = pkgs.fetchurl {

url = "https://www.bioconductor.org/packages/release/bioc/src/contrib/S4Arrays_1.8.1.tar.gz";

hash = "sha256-8f2oA0xgwI6CucXbMU1yJC4W6tiVMcDAk8D3Ur3zxw8=";

};
