Try the R-Sig-Geo mailing list for a better target community, but if these
are shapefiles there is read support in rgdal (or maptools for a simpler
alternative) and if these are in long-lat like the maps package then
plot(x, add=TRUE) will be most of the way there.

This sounds a little bit like homework (since you know the actual

I'd do something like:
