Jupyter notebooks for R

This seems very simple and is well-supported by GitHub. This (click on 'Welcome R - demo) shows a simple example of what a finished notebook might look like.

To write/run notebooks locally:

• Install iPython notebook (+ Python if you don't already have it)
• Install the R kernel for Jupyter
• Run the notebook (opens in web browser)

Haven't tested getting notebooks on GitHub myself but apparently it as simple as commiting a .ipynb file to a new or existing repository. It all works from the cloud so no need for our course attendees to have anything special installed to view/edit/run the notebook.
