Dear useRs:
I try to plot an rpart object but cannot get a nice tree structure plot. I
am using plot.rpart and text.rpart (please see below) but the branches that
connect the nodes overlap the text in the ellipses and rectangles. Is there
a way to get a clean nice tree plot (as in the Rpart Mayo report)? I work
under Windows and use R2.11.1 with rpart version 3.1-46.
You could check out whether you like the plots generated in the "party"
package better. See example("ctree", package = "party").
If you like the plots but don't want to use ctree() instead of rpart():
Then you could install the "partykit" package from R-Forge and then do
plot(as.party(...)) for your "rpart" object.

Thank you.
