Good Looking Maps in R

I haven't yet tried this, but it looks like a nice package.

In one recent project I needed to draw several maps and visualize different kinds of geographical data on it. I found the combination of R/ggplot/maps package extremely flexible and powerful, and produce nice looking map based visualizations.

Here is a short tutorial, monospace font indicates the code you need to run in R. You probably need some basic understanding of R to work through this tutorial.



  1. Hey Tony, this is Rory. Have you ever tried the 'RgoogleMaps' package? It took a little bit of reading but I made some simple plots with lat/long coordinates and it was cool because I could just lay them over a Google map.

  2. Rory,

    I haven't tried it, but I should add that to my list of packages to try out. Thanks for the pointer!
