Subject: paste dependent variable in formula (rpart)?
Hello,
i'm trying to replace different target variables in rpart with a
function. The data.frame getting always the target variable as last column.
Try below, i get the target variable in the explained variables, too!?
Have anybody an advice to avoid this.
rp1 <- rpart(eval(parse(text=paste(names(train[length(train)])))) ~ . ,
data=train,cp=0.0001)
regards & many thanks
Christian
