Yesterday's Introduction to R for Data Mining webinar was a record setter, with more than 2000 registrants and more than 700 attending the live session presented by Joe Rickert. If you missed it, I've embedded the video replay below, and Joe's slides (with links to many useful resources) are also available.
During the webinar, Joe demoed several examples of data mining with R packages, including rattle, caret, and RevoScaleR from Revolution R Enteprise. If you want to adapt Joe's demos for your own data mining ends, Joe has made his scripts and data files available for download on github.
