Hi R users:

I'm an old S user and have just discovered R. I'm having trouble getting
rpart() to grow a tree like tree() does in S. I've checked closely: tree()
in S grows my tree using the call:

tree(putd4313 ~  incpov1+racekid+sex+agegrp+m.agegrp , data = dat ,
subset=set )

but

rpart( putd4313 ~  incpov1+racekid+sex+agegrp+m.agegrp , data = dat ,
subset=set , method='anova' )

in R does not.

Would you kindly suggest what I'm doing wrong in R?

Thanks,
Phil Smith
