Bill - The behavior of the old-S function printer() was to count overstrikes in the way you describe. This was a non-graphics output device which would make a crude scatterplot using ascii characters (spaces and asterisks, for example) in response to "plot()" commands.
I've looked for "printer" in help(Devices) and I don't find it. Non-graphics scatterplots probably haven't been implemented for R yet, and probably aren't a high priority. I think you'll have to count the overstrikes at each location yourself (hash the x-y coordinates), and then use the function text() to plot the appropriate symbol at each x-y location. - tom blackwell - university of michigan medical - ann arbor - On Fri, 3 Jan 2003, Simpson, William wrote: > If I make a scatterplot and several (e.g. 5) points lie on top of each other > at a given x,y location I would like the plot symbol to be the number of > superimposed points (e.g. "5").
