Hmisc and Lattice question on gridlines

I have been using lattice xyplot and am quite pleased, and I can use the
type=c("b","g") to have it print gridlines into the page, yet if I want to
have a line plot with points on it, how do I get the xYplot to print
gridlines (I use Hmisc xYplot because of its bands method which allows
plotting of confidence intervals). Any suggestions? I have looked at the
panel functions but when I try it I get the gridlines but my data is gone.
So a simple example is below. I want to create the reference lines in the
lattice plot in the xYplot from Hmisc so I can keep the confidence intervals
filled.
x<-seq(1,10,1)
y<-seq(1,10,1)
ci<-y*.10
ciupper<-y+ci
cilower<-y-ci
xyplot(y~x, type=c("b","g"),plot.points = TRUE)#using lattice
xYplot(Cbind(y,cilower,ciupper)~x,col.fill="grey",plot.points =
TRUE,type=c("b"),method="filled bands")#using Hmisc
As ?panel.xyplot tells you, type="g" is just a shortcut that calls
panel.grid(), so you get the equivalent effect with
xYplot(Cbind(y,cilower,ciupper)~x,col.fill="grey",plot.points = TRUE,
type="b",method="filled bands",
panel = function(...) {
panel.grid(h = -1, v = -1)
panel.xYplot(...)
})
