Dear Dr. Hijman,
Thank you for the reply.
Initially I was thinking in using a GIS approach, as a state map would to be
involved in the process.
Please check this link: http://img836.imageshack.us/img836/7021/fig6vdist.png
A work colleague produced this map using ArcGIS, but at a cost of almost a
entire morning.
I was wondering if it is possible to reproduce that using R + GIS packages.
Best regards,
Thiago.

Dear Thiago,
If you are using (basic) 'plot' you can pass a vector with the
required sizes, i.e. your variable, perhaps after a transformation, as
cex argument. Same approach works for col.
plot(1:10, cex=c(1:5,1:5), col=rep(c('red', 'blue'), each=5), pch=20)
