patterned non-random jitter

Hi, Is there a function somewhere that does a "patterned" jitter of data? I've googled and the problem is that I don't know what to google for. The setting is in grouped data. I have plots which overlay jittered points on a boxplot. I simply jitter the "x-value", and the "y-value" has no effect. Scientists I work with frequently show plots made by another software where the jitter looks like a bunch smiles stacked on top of each other. The jitter isn't random, but instead depends on the "y-value" somehow.
Hi Daryl, have a look at the code for the cluster.overplot and brkdn.plot functions in the plotrix package. These functions offset the points by regular intervals to avoid overplotting. Jim
