Hi Toby and Maria,
I did a check on Toby's suggestion and it is not there:
R version 2.12.1 (2010-12-16)
> ??barploterrbar
No help files found with alias or concept or title matching
'barploterrbar' using fuzzy matching.
Also I went to the following location which does not exist.

To Maria: here is a suggestion: to do the barplot with confidence
intervals / errorbars:
look at the following R news under www.r-project.org
"An introduction to using R's base graphics." (see following citation)
on page 4 you will find explanations and code how to build bars with se.
