Hi,

I use the spplot function from the sp package, it uses lattice to make spatial plots. The sp-package provides spatial classes for R. See http://r-spatial.sourceforge.net/ for more information on the use of spatial data in R, http://r-spatial.sourceforge.net/gallery/ gives a gallery of spatial plots with the R code it was created by. For questions on spatial data in R the r-sig-geo mailing list is also a good option (https://stat.ethz.ch/mailman/listinfo/r-sig-geo).

hope this helps!
