[R-sig-Geo] spplot help, please

[Bede-Fazekas Ákos]

Hi Marvin,

this code works fine just as it should work. Which "state map" you need? 
A basemap with terrain/roads/cities/borders? In this case there are 
several possibilities to do that. Have a look at these links, they may 
solve your problem:
