[R] Suggestions for scatter plot of many data

[William Michels]

Hello, In addition to Duncan Mackay's excellent suggestion, I would
recommend Bert Gunter's "stripless" package, for high-density
Trellis-type conditioning plots. See the vignette for examples, and
try out the code for "earthquake" and "barley" plots from the
reference manual.

Sincerely,

W. Michels, Ph.D.
