World Bank data is open to the public for research. This apparently is just the beginning of what is possible with having free access to a lot of really good data sets on socio-economic information. R-chart blog just recently posted saying that an R package was developed as an API to access the World Bank data.
This opens up a lot more data mining opportunities and could just be the start of some great analytic research. I'm really looking forward to seeing what some of the great R minds will find with the World Bank data at their fingertips. Since R is freely available anyway this merger makes sense on all sorts of levels. Happy data mining!
