Hello there. I have a tree with only 13 nodes. See my results below. How
do I get node number that is up to 33? Also, what happen to the missing
node number less than 13?
> rpartModel <- rpart(y~., data=data.frame(y=y,x=x),method="anova",
cp=0.005,
+ minsplit=100, minbucket=50, maxdepth=5)

How do I get the node number printed only for the terminal nodes?
