Dr. Ripley,
Thanks much for your reply. I've attached a representative sample; I apologize for not including this with my previous email.
Best,
John

Without the reproducible example asked for it is hard to tell, but
?text.rpart did say

      ...: Graphical parameters may also be supplied as arguments to
           this function (see 'par').  As labels often extend outside
           the plot region it can be helpful to specify 'xpd = TRUE'.

Might that be the issue (rather than your subject line)?

Hello,

I am relatively new to R and am using it to run Classification and
Regression Tree analysis. My only issue at this point is that numbers
are always cut off on the lower nodes. I've tried changing the margins
with

mai=c(0, 0.5, 0.5, 0) but this has not so far worked.

Any suggestions would be appreciated.

Best,
