I'd like to create a bidimensional presentation of a classification tree built using the rpart() function. I've seen that a partition.tree() function exists for the tree() function. Does a similar function exist for the rpart() function? Thanks a lot Simone Vantini

...nce 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: r-help-bounces at stat.math.e...
