[R-sig-Geo] mapping introduction

[Stan Hopkins]

I was just about ready to option out of this sig group as being too when the 
last few of questions and answers were posted perhaps by beginners like 
myself.

I wonder if there's any way to separate newbie questions from the more 
advanced so that my mailbox isn't flooded with the later.

Thanks,

Stan
