I don't know if anyone has replied to you yet. Your problems appear to
be more elementary than using the tree package. I think you may need to
understand better the concept of data frames in R (the "row names"
need
to be unique, for example, and, although I can't find this stated
explicitly in the documentation, it is certainly enforced).
Nevertheless, before trying to use the tree package again, I suggest you
upgrade R to the latest version (1.5.1) and switch from the tree package
to the rpart package. The rpart package has better diagnostic
facilities and is being more actively maintained.
