The Guerry package contains two maps of france (gfrance, gfrance85) which are quite detailed and large in size (~900K). In writing a vignette for the package, there are quite a few figures that use the map multiple times in a layout, and consequently result in huge file sizes for the .PDF files created. For these purposes, the map need not be nearly
so detailed.

I'm wondering if there is a facility to "thin" the map by drawing it at a lower density of lines in the polygon regions. When I was working with SAS, there was a GREDUCE procedure that did this nicely.
