Hello again,

I'm still confused how this is supposed to work. Especially the symbol for
the outliers still puzzle me. This is what I do:

bwplot (points ~ general[,1] | groups,
        layout = c(1, 3),
        scales = list(x = list(at = seq(10, 100, by=5), labels=seq(10, 100,
by=5), tck=c(1,0))),
        panel=function(x,y) {
           panel.bwplot(x,y, horizontal=FALSE, pch="-", outlty=1, outpch=NA)
           },
        horizontal=FALSE)

The symbol for the outliers don't get changed wheras the "pch"  changes the
symbol for the median. Which parameter changes the outliers?

cheers

Vincent
