Videos from Coursera’s four week course in R by David Smith.
From the post:
Coursera’s Computing for Data Analysis course on R is now over, with four weeks of free, in-depth training on the R language. While you’ll have to wait for the next installment of the course to participate in the full online learning experience, you can still view the lecture videos, courtesy of course presenter Roger Peng’s YouTube page. The course materials are helpfully organized into four video playlists by week; I’ve embedded each week’s content below with an index to the individual video chapters.
Just in case you missed the class or need a refresher!
