WHAT DOES THIS DO?

This is a container that runs R... not any of the R IDEs.

HOW TO RUN IT?

0. Make sure you're on a system running X.
1. Disable X access control (don't do this on a public-facing machine): $ xhost +
2. $ cd to a path where you want to do some R.
3. $ docker run --rm -it -v /tmp/.X11-unix:/tmp/.X11-unix -v `pwd`:`pwd` -e DISPLAY=$DISPLAY -e RWORK=`pwd` hackenfreude/r-3.3.1
4. You'll end up on the R command line. Do some R. If you tell it to plot something, you'll see the plot come up on your screen.
5. > q() will quit R and kill the container. Any files you created will be on the path of the host where you started.
6. Reenable X access control: $ xhost -

WHAT JUST HAPPENED?

• Docker mounted the host's X socket in the continer as the container's X socket; this allows the container's GUI to pass back up to the host. This is only relevant if you plot something.
• Docker mounted the host's working directory in the container at the same path.
• Rprofile.site tells R set its working directory to the RWORK environment variable. Part of the docker run command above sets RWORK in the container as the host's working directory.
