Hello Deepayan,
Thanks for the below solution to my graphing problem - just what I
was looking for.
One quick additional question, where do I change graphical
settings (lwd, pch, etc...) for the added points?
Thanks,
John

If you want to add the same lines/points in all panels, you could
write a not-too-complicated custom panel function; e.g.,
with(dat,
xYplot(Cbind(ycomb, y.up, y.low)~x1|factor(grp),
data=dat,type="l",
method="filled bands",
col.fill="light grey",
subscripts = TRUE,
panel = function(...) {
panel.xYplot(...)
panel.segments(pxlow, pylow, pxhi, pyhi)
},
scales=
list(y=list(relation="free"),
x=list(alternating=c(1,1,1))),
ylim=list(c(0,1200),c(0,10000))))
