Today is Talk Like A Pirate Day, the perfect day to learn R, the programming language of pirates (arrr, matey!). If you have two-and-a-bit hours to spare, Nathaniel Phillips has created a video tutorial YaRrr! The Pirate's Guide to R which will take you through the basics: installation, basic R operations, and the matrix and data frame obects.
For a more in-depth study of R, there's also a 250-page e-book YaRrr! The Pirate’s Guide to R which goes into the basics in more depth, and covers more advanced topics including data visualization, statistical analysis, and writing your own functions.
There's also an accompanying package to the video and book called (appropriately) yarr that includes datasets from the course and also an interesting “Pirate Plot” data visualization that combines raw data, summary statistics, a “bean plot” distribution, and a confidence interval.
For more on The Pirate's Guide to R (and to tip him a beer), follow the link to Nathaniel's blog below.
