Facebook teaches you exploratory data analysis with R

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.   As the name suggests, this online course uses R (via RStudio) and the ggplot2 package to provide an introduction to Exploratory Data Analysis. The R Basics chapter gives a general overview of R: installing, starting, getting help, and language basics. Then the course covers visualizing data sets of one, two and multiple variables. There's even an introduction to predictive modeling at the end of the course. A free Udacity account is required to watch the course videos. Get started at the link below.
