[R] mapping data to a geographic map of Europe

[paladini at trustindata.de]

Hello,
I would like to draw a map of Europe. Each country should be colored  
depending on how it scores in an index called GPIndex.
Say a dark red for real bad countries a light red for those which are  
not so bad, light blue for the fairly good ones and so on up to the  
really good ones in a dark blue.
I never worked with geographic maps before so I tried library maps but  
I didn't get far,- especially because all examples I found only seem  
to work for the United states. So I'm a bit lost.
I would be nice if somebody could help me.

Thanking you in anticipation!

Best regards

Claudia
