[R] plotting points over a map using R

[Barry Rowlingson]

Try reading the R Spatial Task View:

http://cran.r-project.org/web/views/Spatial.html

or this brilliant intro, and other files in that github repository:

https://github.com/Robinlovelace/Creating-maps-in-R/blob/master/intro-spatial.md

or any of the tutorials I've written on the subject!
