Hi David, 

 

May be I was not clear, but I want to label the branches itself and not the branching points or the leaves.

 

Regards

Utkarsh

You may have to change/scale the sizes of the font by using "cex" and then to keep all labels within the plotting window, use "xpd=TRUE". Like in

text(fit, use.n=TRUE, cex=0.8, xpd=TRUE)

When I execute that code, I get labels both on the branching points and at the

leaves of the tree. So I guess my reply is "cannot reproduce" or

"do not understand".  They are however not properly positioned and the

edges and
 bottoms of some of the labels are cut off, but that did not sound like

your question.

  

Using Mac OS X 10.5.6 and the ATT binary of R2.8.1. 'rpart' version 3.1-42.

Note:  your mailer is putting single quotes inside the enclosing angle brackets

so my mailer does not recognize the r-help address as a valid address. Since

this is the first time I have encountered this construction, I wonder if your

mailer is adhering to standards in its reply-to functions.
