Hi Michael, Steve, and 1Rnwb, I'm very impressed by the quick replies on the mailer. Thanks a lot for your suggestions. They worked very well.
In general, I have to say that I'm a bit disappointed that in R, like in Excel, one basically needs to hack to get a dot blot with categories by adding an artificial x value. I was hoping this common type of diagram could be generated using a standard function like dotplot or dotchart.
