I need to do something quite simple, but a search of the "CRAN Task View:
Analysis of Spatial Data" has not revealed to me the best way to do this.
What I would like to do is plot a map of the U.S. with each state's color
corresponding to heatmap colors of a population statistic. For example, dark
red could be a state with the highest number of H1N1 cases, pink with an
intermediate number, and white with no cases. An ability to overlay the
center of the state with the actual statistic would be nice but not
necessary.

Is there a straightforward method to accomplish this? A vignette perhaps?

Thanks,

Mark
