Hi,

I'm trying to plot a set of geographical coordinates over the polygons in a
shapefile, so I need to transform the coordinates to the same projection.
I'm currently using the project function in the rgdal library, but I can't
seem to figure out how to format the proj string argument correctly. (I made
a couple attempts using http://www.remotesensing.org/geotiff/proj_list/ as a
reference.) I've never done worked with geographical data in R before so I
thought I'd see if someone more experienced could help. The text of the .prj
file is included below.

Thanks!
Patrick
