   Can someone point me to a justification for the design
decisions, which seem to be similar in lattice and
ggplot2, of (1) gray backgrounds and (2) filled points?
[I seem to remember seeing somewhere the opposite recommendation
for points, i.e. that open points make it much easier to
see if there are overlapping values -- and this would
be a reason that pch=1 gives an open circle ...]

   cheers
