R help - Dec 2008 - R Graphics Device margins

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,

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)?

Try par(xpd=NA) to turn of clipping (that's from memory, so ?par if that
does not work). Also it is often helpful to set plot margins (mar) to zero
and set outer margins (oma) to some reasonable values.
