  Hello, Matthew.
  Just a superb complement of yours.
  I was about to ask the same question to Pierre and Paul, after thanking them for the useful and functional tip. I managed to follow the ggplot examples, but a next step would involve plotting my interest points over a shape file (state contour). 
  Is that possible?
  Best wishes,
  Thiago.

 I've been following this topic with some interest, since this is something I might like to do fairly often.  I'm not that familiar with ggplot2, but it looks really useful.  Is there a way to overplot (or underplot) a shapefile (e.g. of coastlines) with the approach suggested by Paul?
