 Rpart has a built in cross-validation proceedure.  the xerror and so on 
are based on a ten fold cross validation, I believe.  Read the manual 
for more results.  If you plot the fit with post and then look at the 
postscript file it should have a misclassification rate under the 
terminal nodes.
HTH,

Stephen
