R Lectures

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.

All questions to matt@wmbriggs.com.

    Thank you for your efforts on this. I began playing with R in December – what a great tool. But I have much yet to learn and look forward to future installments in your tutorials!

    That was quick!

    I posted my comment about needing a category for R lectures, and when the page reloaded, there was a category R-lectures! I have never had a blogger respond to a suggestion so quickly before (actually, I have never had a blogger respond to a suggestion before — but I’m sure they’ll answer me once they get to my comment).
