This is the homepage for the links to all of the R lectures. Look for this on the main page under Statistics.
Each lecture is followed by a difficulty number, higher means more work on your part. The progression of difficulty will be, more or less, straightforward, but there will be occasional departures for subjects that strike my fancy.
All videos are on YouTube under the username “mattstat” (wmbriggs was taken). That service imposes a ten-minute limit of videos. Accordingly, lectures are short.
