Hi, I have read about the use of symbols() to draw circles of different sizes, but I have not been able to find out how to add a legend to such a graph, legend that would display some specific sizes and their meaning.
Before finding the symbols function in Paul Murrell's book, I had rolled by own function where the variable I want to use to control circle size was actually used to control cex. I was able to draw a legend afterward. Symbols seems a bit simpler and I wanted to see if it would be better than my own function. But without legend it is less useful. However I'm sure there is a way which I'm not aware of to draw a legend for a plot drawn with symbols()... Thanks in advance, Denis Chabot ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
