I might well be wrong, but I don't think there is. I went about rewriting partition.tree for rpart once but stopped after I realized that it was much easier to add lines and segments to plots by hand using the coordinates from the rpart object (I then added a third predictor to my dataset making the whole process pointless anyways.) Looking at the code for partition.tree and its embedded function ptXlines gives you hints how to extract the relevant bits of the tree to add to a plot.
I assume that you've seen this thread? http://www.r-project.org/nocvs/mail/r-help/2002/0142.html Sorry not to have been more help. -Andy > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Simone Vantini > Sent: Wednesday, November 10, 2004 5:27 AM > To: [EMAIL PROTECTED] > Subject: [R] Does something like partition.rpart() exist? > > > I'd like to create a bidimensional presentation of a classification tree > built using the rpart() function.
