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) Robert On Mon, Aug 23, 2010 at 7:26 AM, Thiago Veloso <thi_vel...@yahoo.com.br> wrote: > Dear SIG colleagues, > In my present study I need to plot a map containing two different > attributes of some localities.
