[R] How to plot data using ggplot

[Dennis Murphy]

1. Look into the ggmap package if you want to overlay your data onto a map.
2. Re your color scale representation, define 'appropriately'. Do you
mean a continuous range expressible in a colorbar or a discrete range,
and if the latter, what intervals did you have in mind?
