R help - Aug 2000 - pattern on bars?

Colors are real nice, but the publication I'm preparing these barplots for
permits only black and white. The Splus plot options ``dbangle''  (or
plain
``angle'') and ``density'' (as on p. 65 of MASS 1st ed.)
don't seem to be
available in R.  Is there another way to do this?

I'm running R 1.1.0 on Linux (intel). Thanks.

Use a grayscale color palette.  If I remember right, R's grayscales are
quite well printed on a B/W printer (and if I remember properly, much
better than S-plus' grayscales).

Try the following example  

   postscript("gray-bars.ps")

   data(VADeaths, package = "base")
   barplot(VADeaths, col = gray(seq(0,.9, len=6)))

   dev.off()
   system("gv gray-bars.ps &")

Certainly there are ways to do this.
One of the many ways is to use something like "col = gray...".

I've attached an example below:
csd <- matrix(c(4,  2,  4,  6,
                4,  3,  1,  4,
                4,  7,  7,  1,
                0,  7,  3,  2,
                4,  5,  3,  2,
                5,  4,  2,  2,
                3,  1,  3,  0,
                4,  4,  6,  7,
                1, 10,  8,  7,
                1,  5,  3,  2,
                1,  5,  2,  1,
                4,  1,  4,  3,
                0,  3,  0,  6,
                2,  1,  5,  5),
              nr = 4)

barplot(csd,
        col = gray(5:9/10), # Use monochrome
        ylim = c(0,30),
        names = 72:85, xlab="Year", ylab="Students",
        legend = c("Winter", "Spring", "Summer",
"Fall"),
        main = "Graduated PHD - CSD")

Cheers,
