Hello all,
I have a question concerning the trellis panel boxplots. I would like
to draw series of _vertical_ boxplots in different panels and connect the
medians within each panel with a line.
Two questions:
a) bwplot(x ~ y|z) draws the boxplots _horizontally_: y is the horizontal
axis and x is the vertical axis giving the groups. I want to have it
just the other way around - does anybody know how to do that in order
to get _vertical_ boxplots??
b) how can I connect the medians in each panel.boxplot? I am thinking
of using tapply(y,factor(x),median) and add it by lines(), but I do
not know how to do it inside each panel...
any help?
thanks a million in advance
Matthias
