R

R is a "free software environment for statistical computing and graphics."

Installation

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.

In practice, R is commonly written inside editors like RStudio or inside a Jupyter Notebook.

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 ]; };
