R help - Jan 2003 - [lattice] lines for stripplot (like dotplot) or jitter for dotplot?

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

You could jitter your data manually using jitter() (part of the base
package) and then use dotplot.

Hope this helps,

In stripplot, try with something like

  panel = function(x, y, ...) {
      panel.abline(h = unique(as.numeric(y)), col = "grey")
      panel.stripplot(x, y, ...)
  }

(or more generally, with col = trellis.par.get("reference.line")$col
etc)
