Hi!
I recently posted a similar question (entitled "Adding mean line to a
lattice density plot"). Have not got any usable solution forcing my to
fall back to the use of the normal 'plot' function. The problem was the
same as yours: using panel.abline simply did not work, the position of
the mean line was incorrect. I have posted a workaround (based on plot),
please see my earlier posting.
HTH,

by simply adding another call to panel.abline () seems not producing a
correct result for each panel
# medians and means for each panel:
dotplot(variety ~ yield | site, data = barley,
scales=list(x=list(log=TRUE)),
layout = c(1,6),
panel = function(x,y,...) {
panel.dotplot(x,y,...)
median.values<- median(x)
panel.abline(v=median.values, col.line="red")
mean.values<- mean(x)
panel.abline(v=mean.values, col.line="red")
})
In the dataset I'm currently working on (which is not the above mentioned
example) I've got a wrong plottting of the means for each panel, what I'm
missing?
thanks
