>Is there any way to fill the bars in a barplot() with solid lines for
postscript output, i.e. cross hatch or parallel lines, or a halftone gray
rather than (semi) continuous-tone gray produced by gray()? S allows this,
or at least used to, via the angle and density arguments to barplot(). The
objective of course, is to produce camera ready black and white plots on a
laser printer. The gray values produced by gray() do not reproduce well.
implementing density and angle arguments are on the todo list. the bad news
is that they're behind a number of more important bugs. the good news is
that they get closer to the front of the todo list as more people request it
