Barplots

Hello,
Can anyone tell me how to label individual bars on a barplot?  I want
to put an "*" or letter ABOVE the bar to denote statistical
significance.  Is this possible and how?

Thanks,
Suzanne

You might want to take a look at the most recent issue of R News, which
has an article on R's base graphics, that contains an example of an
annotated barplot(). There is also a graphic of the output.

HINT:  barplot() returns the bar midpoints (ie. mp <- barplot(....))

HTH,
