R help - Apr 2004 - How to draw a tree?

Hi,

I have run rpart to construct a regression tree. Is there any simple
method to draw a nice picture of it, as it is usually done in books and
paper to visualize the tree?

Thank you,
Christian

See ?post.rpart.  That's probably as good as it'll get.  You might also
want
to look at the maptree package on CRAN.

Christian,

rpobj <- rpart(....)
plot(rpobj)
text(rpobj)

See ?plot.rpart and ?text.rpart for details on how to tune the 
visualization.
