Dear Mayeul, Thanks for your tip. I am surely going to analyse the code and try to reproduce it. But instead of colouring the municipalities, the only variable I need to work with would be the indicative circles, something like this example: http://img836.imageshack.us/img836/7021/fig6vdist.png Best wishes, Thiago.

Same approach works for col. plot(1:10, cex=c(1:5,1:5), col=rep(c('red', 'blue'), each=5), pch=20) Robert ote: > Dear SIG colleagues, > In my present study I need to plot a map containing two different attributes of some localities. I figured out that a convenient and didactic way would be via something like bubble plots. 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. > Is it possible to implement that idea using SIG tools in R?
