R help - May 2017 - Offset - usersplits function package RPART

I have written a user written splitting function recently, but I do not know how
to use my splitting criteria to predict the test data. If I use the function
?predict?, there will return an error message, please give me some helpful
advice.

`predict`-methods are functions written to deliver results from a particular
class. Look at:

 methods(predict)

Sometimes there is a func.default method for a generic function named `func`,
but rather predictably I would say, there is no such default in the case of
`predict`.
