R help - Oct 2009 - How to draw more geographical boundaries

Dear R-users,

I am trying to plot in the same map both NUTS 2 (i.e. regional) and NUTS 3 (i.e.
provincial) boundaries for Italy
but I couldn't find how to plot more than one level boundary in the same
map.//
//
I have shapefile both for regions and provinces in Italy and I tried to use the
"maptool" and "maps" packages without
success.

Thank you in advance for any help.

Best regards,
Angela Parenti/
