I demonstrate how to use dplyr for data manipulation in R (R code and data on GitHub ). I had heard of the package before and finally gave it a try after attending Hadley Wickham's presentation at useR! in LA a couple of months ago. dplyr will change your life as it relates to data manipulation!
There are plenty of other R blogs out there, but I wanted to cover practical statistics topics in video format. Video lectures got me through my dissertation and I want to repay some of the favor. If you have a good idea for a video or need some help, let me know!

GBMs are awesome: Part I
GBMs have become my favorite type of model over the last two years. In this tutorial, I demonstrate how to use a GBM for binary classification in R (predicting whether an event occurs or not). I also discuss basic model tuning and model inference with GBMs. Stay tuned for a second part focused on tuning parameters, variable selection, and cross validation with GBM!
