R comes with a very large number of packages, many of which available through nixpkgs. In particular, any package available through CRAN.
Similarly to Python, your packages must be declared when installing R. Commands such as install.packages("ggplot2")
will not work.
To install R with a collection of packages, a new nix package must be defined, for instance
with pkgs;
let
R-with-my-packages = rWrapper.override{ packages = with rPackages; [ ggplot2 dplyr xts ]; };
in ...
and then you can put R-with-my-packages
into your environment.systemPackages
for a system-wide installation, for instance.
If you with to use `nix-shell` to generate an on-the-fly environment with some R packages, the command is similar:
nix-shell --packages 'rWrapper.override{packages = [ rPackages.ggplot2 ];}'
RStudio
RStudio uses a standard set of packages and ignores any custom R environments, like the one set up above. To install it you can use rstudioWrapper
just as we used rWrapper
earlier.
RStudio-with-my-packages = rstudioWrapper.override{ packages = with rPackages; [ ggplot2 dplyr xts ]; };
Jupyter Notebook
There is currently no package in nixpkgs to set up Jupyter Notebook with additional kernels. (Keep an eye on this this pull request though).
For now, you can save the following into a file and run it with nix-shell:
with import <nixpkgs> {};
let
my-R-packages = with rPackages; [ ggplot2 dplyr xts ];
R-with-my-packages = rWrapper.override{ packages = with rPackages; my-R-packages ++ [ JuniperKernel ]; };
jupyter-R-kernel = stdenv.mkDerivation {
name = "jupyter-R-kernel";
buildInputs = [ pythonPackages.notebook R-with-my-packages ];
unpackPhase = ":";
installPhase = ''
export HOME=$TMP
${R-with-my-packages}/bin/R --slave -e "JuniperKernel::installJuniper(prefix='$out')"
'';
};
in
mkShell rec {
name = "jupyter-with-R-kernel";
buildInputs = [ jupyter-R-kernel ];
shellHook = ''
export JUPYTER_PATH=${jupyter-R-kernel}/share/jupyter
# see https://github.com/NixOS/nixpkgs/issues/38733
${R-with-my-packages}/bin/R --slave -e "system2('jupyter', 'notebook')"
'';
}
How does rWrapper
work?
rWrapper
simply replaces the R command in your path by a script that sets the environment variable R_LIBS_SITE
and then runs R. [1]
With nix-shell
Below is an example of a nix-shell build to run R with knitr for R markdown:
default.nix
let
pkgs = import <nixpkgs> {};
stdenv = pkgs.stdenv;
in with pkgs; {
myProject = stdenv.mkDerivation {
name = "Speedracer";
version = "1";
src = if pkgs.lib.inNixShell then null else nix;
buildInputs = [
R
rPackages.knitr
rPackages.rmarkdown
];
};
}
R with Lorri
An example of a shell.nix for usage with lorri is shown below:
let
pkgs = import <nixpkgs> {};
in
pkgs.mkShell {
buildInputs = with pkgs; [
R
rPackages.rmarkdown
rPackages.knitr
];
}
Other Editors
with vim - nvim-r
Note - if you are building an environment and plan on using nvim-r, it cannot also include rstudio, it will break your packages!
with emacs - emacs speaks statistics
