[R] How do you rotate axes in ctree - (Party Package)

[Christopher Choi]

I have a classification tree analyzed using ctree() was wondering how
can one rotate the terminal nodes so that the axes are vertical?

library(party)
data(iris)
attach(iris)
plot(ctree(Species ~ Sepal.Length + Sepel.Width + Petal.Length +
Petal.Width, data = iris))
