Facebook teaches you exploratory data analysis with R by David Smith.
From the post:
Facebook is a company that deals with a lot of data — more than 500 terabytes a day — and R is widely used at Facebook to visualize and analyze that data. Applications of R at Facebook include user behaviour, content trends, human resources and even graphics for the IPO prospectus. Now, four R users at Facebook (Moira Burke, Chris Saden, Dean Eckles and Solomon Messing) share their experiences using R at Facebook in a new Udacity on-line course, Exploratory Data Analysis.
The more data you explore, the better data explorer you will be!
Enjoy!
