That's wrong (it used to be right - a good example of why \synopsis is bad). Since lattice 0.13-x, panel.superpose is never the default panel function. An updated version with improved documentation should be out soon. 'panel.groups' is simply an argument to panel.superpose, and is described in ?panel.superpose. Thus, it only makes sense as an argument to xyplot/dotplot/whatever when the panel function is panel.superpose, and not otherwise. The entry for the graphical parameters in ?panel.superpose isn't as useful as it could be, I have just updated it to read: col, col.line, col.symbol, pch, cex, fill, font, fontface, fontfamily, lty, lwd, alpha: graphical parameters, replicated to be as long as the number of groups.

Re: [R] dotplot (lattice) with panel.segments and groups
Could you explain what panel.groups= does and what the difference
is between panel.groups= and panel= ? In ?xyplot it just says:
panel.groups: useful mostly for 'xyplot' and 'densityplot'. Applies
when 'panel' is 'panel.superpose' (which happens by default
in these cases if 'groups' is non-null)
which indicates when it might apply but not what it does.
Also can we assume from the above that the panel=panel.superpose
in your response could have been omitted?
Thanks.

It's just as it says: panel.dotplot wants a 'subscripts' argument when
'groups' is not null, and you have forgotten to give it one.

It's doing what it's being told to do. You probably want something like
dotplot(site ~ yield | variety, data=barley,
groups=year, yield2=barley$yield2,
col=c("gray", "black"),
panel = panel.superpose,
panel.groups = function(x, y, subscripts, yield2, col, ...) {
panel.xyplot(x, y, col = col, ...)
panel.segments(x, y, yield2[subscripts], y, col = col)
})
Note that you don't want to use panel.dotplot here as it would draw a
reference line both times. If you do want a reference line, add that
in the panel function.
The explicit use of 'col' should not have been necessary, i.e., the
following should have worked:
dotplot(site ~ yield | variety, data=barley,
groups=year, yield2=barley$yield2,
col=c("gray", "black"),
panel = panel.superpose,
panel.groups = function(x, y, subscripts, yield2, ...) {
panel.xyplot(x, y, col = ...)
panel.segments(x, y, yield2[subscripts], y, ...)
})
I believe this doesn't work because of a grid bug. I'll take that up
in a separate thread.

Re: [R] dotplot (lattice) with panel.segments and groups
It seems to work if you handle the col= argument explicitly.
Suggest you double check this since I have not carefully done so:
barley$yield2 <- with(barley, yield + 5)
dotplot(site ~ yield | variety, data=barley, groups=year,
yield2=barley$yield2, col=c("gray", "black"),
panel=function(x, y, subscripts, groups, yield2, col, ...) {
panel.dotplot(x, y, ...)
panel.segments(x, as.numeric(y),
yield2[subscripts], as.numeric(y),
col = col[groups[subscripts]], ...)
})
