Did you look at package maptools? I haven't myself delved into any of the other mapping packages, but I understand that maptools will handle shapefiles, which are generally freely available for the US states (and most countries). See e.g. http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html for a description, then ftp://ftp2.census.gov/geo/pvs/tiger2010st/ to get the county numbers, then ftp://ftp2.census.gov/geo/tiger/TIGER2010/COUNTY/2010/ to download the relevant shapefiles.
