A review of ggmap (2.1)

Basic functions work like a charm!

At this point I've only used the basic get_map() and ggmap() functions, but they're easy to learn, easy to use, and produce beautiful results. I was able to go from initial installation to having a satellite photo aligned perfectly with my polygon map in less than 30 minutes. Tip for using: write your ggplot2 code as if you'll be invoking ggplot() with no arguments, and then substitute ggmap(nameofggmapobject) for ggplot().
