Advanced R Programming (And Why that is Important)

Thanks to Reddit.com/r/programming for directing me to this excellent compilation of R programming information by Hadley Wickham.

Most of us in analytics use R just to get stuff done. It has a large number of packages that lets us produce insights at our own pace.

GoogleVis - Create Interactive Maps Online with Data in R

Creating interactive maps is typically either difficult (e.g. openheatmap) or expensive (e.g. ESRI).

It displays graduation rates by states, mousing over a state provides its name and given graduation rate. After the map is quick tutorial on how to do it.
