[R] 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.

Cheers,
Bert
