Doh, can't believe I missed that. Sorry Bert.

See segplot in the latticeExtra package.

Well, the OP already referred to segplot.
But, see, he shouldn't be doing this plot in the first place. Yes, I
know it's fairly standard in science, but it's a bad idea (as are many
others, like the infamous dynamite plot). If uncertainty intervals
are desired, they should be model based,
You might want to look at the examples in error.bars.by in the psych package.

Hi Jun,
Here is one way to do this using the mtcars data set, although there
are probably better ways.
mtcars$sd-runif(32,1,2)
mpgxhp-xyplot(mpg~hp,mtcars,
main=Miles per gallon by horsepower,
xlab=Horsepower,ylab=Miles per gallon,
panel=function(x,y,ulim,llim) {
yspace-diff(range(y))/100
Dear list,
I have a couple of lines (superimposed) in an xyplot and just want to add
error bars to each of the data point. It's been a while since this question
was asked last time. But the segplot from latticeExtra is not straight
forward. Just wonder if there is a better way to do this.
