[R] [lattice] lines for stripplot (like dotplot) or jitter for dotplot?

[Michael A. Miller]

I'd like to use stripplot for some plots because I want to use
the jitter parameter.  On the other hand, I'd like to use dotplot
because I'd like to have the horizontal lines that it includes.
dotplot doesn't have a jitter option and I'm not having any
success with getting panel.grid(h=-1) with stripplot.  Can anyone
show me how to make dotplot-like lines on a stripplot?  Or how to
jitter the vertical plotting position on a dotplot?

Thanks, Mike
