Folks:
I found the references in the previous replies to this vexing data visualization issue to be quite interesting and useful. I think it fair to say that there is no single "best" way to do this -- it all depends on what you need to learn , and probably several alternative displays will be necessary to get the important information the data have to convey. However,as always, this issue has been considered before, and it may be worthwhile to at least consider an already available "standard" approach" using shingles and a trellis-type plot. ?xyplot and ?shingle should get you started (you probably want to shingle or bin on quantiles of y). The canonical reference is Bill Cleveland's VISUALIZING DATA (see "coplots").

Karin, I like to use bagplots in these cases where there are a lot of cases and scatter plots become one big smudge.
