guslDear LJ Genie,
Sometimes I make two-color scatterplots with o-shaped points. Occasionally, when I have a few thousand points, they bunch up and it really matters which color was plotted first: I can't see behind the color that was plotted last... except when Acrobat refreshes its window.
...which of course means it's possible to manipulate the elements of a PDF. But how?
Ideally, these points would be plotted at a random order (independent of color) AND would be semi-transparent. I'm not sure how to accomplish this easily with R's 'plot'.
