Hi, Thanks for the replies. I am not good enough in R to really hack the legend function but i can grasp what is all about. Actually i tried different cex.pt, pt.cex, and any other number of combinations between cex and pt and pch hopping one might be a parameter in the function .... Oh well .... But pt.cex would be a nice addition - i think. Meanwhile Peter's solution seems more close to my abilities and understanding R so i will try that one. But i am looking forward for the improved legend. Thanks again, Monica
