R help - Sep 2011 - Need formatting help - ctree - plot.party - node_hist

Hi,
I am trying to get the terminal nodes of a plot of a ctree object to look nice.

Using the iris data I have:

library(party)
mtree <- ctree(Species ~ ., data=iris)
plot(mtree,terminal_panel=node_barplot(mtree))

The terminal nodes don't display the species names because the names
are displayed horizontally. ?I would like to reduce the size of the
labels and make the terminal nodes horizontal barplots or rotate the
labels by 90 degrees, but I don't know how to do this. ?Any help is
appreciated.

Warren

Hi,

You can get something better in this way:

plot(mtree,terminal_panel=node_barplot(mtree, ylines=1.2, gap=0.05))


Check node_barplot() for details, although it does not offer for barplots
the possibility to graph it horizontally.
