[R-sig-Geo] Mapping multiple attributes at once

[Robert J. Hijmans]

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)

For example, the size of the circle would be proportional to a certain range of values (4 categories) and its inner colors (also 4 categories) would be proportional to the p-values of a statistical test.
