The site twotutorials has more than 90 two minute video clips on various uses for R.  The clips minimise prerequisite knowledge and are super entertaining to watch.  They begin with installing R then work through a range of topics that will be of interest to statisticians and data analysts including:

  • how to read and write excel files with the xlsx package
  • what does the %in% operator do and how does it differ from the double equals (==) sign?
  • how to merge stuff together using the merge, cbind, rbind, and rbind.fill functions
  • how to run your first regression
