R help - Jan 2009 - Bar Plot ggplot2 Filling bars with cross hatching

#I am putting a test together for an introductory biology class and I
would like to put different cross hatching inside of each bar for the
bar plot below

color <- c("Brightly Colored", "Dull",
"Neither")
lizards <- c(277, 70, 3)
liz.col <- data.frame(color, lizards)
qplot(color, lizards, data=liz.col, geom="bar", ylab="Observed
Matings", main="Counts Out of 350 Aquariums", ylim=c(0,400),
fill=color)+scale_y_continuous(breaks=c(0, 70, 277, 350))


Thanks

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.

Also notice that the q in Aquarium is hidden.  Is there a way to make
this not happen?
thanks

Hi Stephen,

ggplot2 uses the grid package to do all the drawing, and currently
grid doesn't support cross-hatching, so unfortunately there's no way
to do this in ggplot2.

If classic graphics is ok try this which uses hatches and different
shades of grey:

barplot(lizards, names.arg = color, col = grey(c(.2, .5, 1)), density = 20,
    angle = c(45, -45, 0), legend = color)
