plot_map() - Tutorial

My first complete function is plot_map(). This function builds upon functions in the ggmap and ggplot2 packages to give a (hopefully) user-friendly, data in -> plot out interface. For an example check out the nice video I made on the homepage where the pigeons are making their way home as a group through beautiful Surrey hills.
