Thank you for your answer. I have about 7 stacks it is not very appealing to have just
stripes with changing angles. I was wondering if there is a way to have varying
patters in black and white.

Hi
This is what help page says about colours and shading lines
density: a vector giving the density of shading lines, in lines per
inch, for the bars or bar components. The default value of
'NULL' means that no shading lines are drawn. Non-positive
values of 'density' also inhibit the drawing of shading
lines.
angle: the slope of shading lines, given as an angle in degrees
(counter-clockwise), for the bars or bar components.
col: a vector of colors for the bars or bar components.
Do you want something else than
barplot(1:3, col=c(2,3,3),density=c(2,4,6), angle=c(30,60,90))
Cheers
