Did you look at the documentation for bwplot and panel.bwplot?
This should do it , adjust at will:
ex <- data.frame(x=1:10, y=rep(c("A","B"), 5))
bwplot(y~x, data=ex, panel=function(x,y,...) {
panel.bwplot(x, y, pch="|", ...)
panel.points(mean(x), y, col="red", ...)
})
If you want the mean lines to appear as lines as well, you'll likely
want to look into the actual code of panel.bwplot, to see what it
does when pch="|".
