Dear Paul,
Thanks. Redrawing the points solves it for the minimal example, but what happens
if you have plot(.., type="b") like below?
Actually, originally I wanted to use just grid (without mixing it with base
graphics), but I couldn't find an equivalent for plot(.., type="b"). Also, later
on, I would like to use eaxis() to draw nice y-axes in log-scale. I guess that's
easier with gridBase then.
Cheers,
Marius
