I am trying to predict a target variable that takes values 0 or 1 using the rpart command. In my initial dataset I have few positive observations of the target variable; therefore I have oversampled the rare event by a multiple of 6 (i.e. from 762 to 4572).
However, in my results, I end up with a number of positives in one of the terminal nodes that is not divisible by 6. As I have the

which I need to write a report in two hours. I have spent 10,000
