Thank you.  Downloaded Hmisc using the Packages
button in the RGUI for Windows.  My hat's off to the programmers...
the system of downloading and installing a package works like a champ.
I then tried your code and it too works great.

I've added your suggested http://cran.r-project.org/search.html
to my Favorites list.  Very helpful.
Merry Christmas
REX

See errbar in Hmisc. I found this with:

help.search("error bar")

And it's in the html help too. And on the r site:
http://cran.r-project.org/search.html
http://www.google.com/search?q=error+bar&domains=r-project.org&sitesearc
h=r-project.org

# Example
require(Hmisc)
set.seed(1)
x <- 1:10
y <- x + rnorm(10)
delta <- runif(10)
errbar( x, y, y + delta, y - delta )

HTH, Andy
