How to add error bars to a line xyplot (lattice 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, obtained,e.g. by the relevant predict() method. But this is OT for here, so I won't rant further.

See segplot in the latticeExtra package. Kevin On Mon, Jan 26, 2015 at 7:58 PM, Jun Shen <jun.shen.ut at gmail.com> wrote:
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. Appreciate for
any comment. Thanks.
