- A note about the videos in this tutorial: they are from Roger Peng's YouTube channel on R Videos. He is running a MOOC on Computing for Data Analysis which started on 2 January, and is currently running.
Not every aspect about R can be covered with our tutorial (above). Here are some additional resources.
- Cookbook for R: how to work with numbers, manipulate data, statistical analysis, graphs, debug scripts
- Another good tutorial, Quick-R: follow the links on the left-hand side
- The two-minute tutorials on many R-related aspects
