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)])))) ~ . ,
I guess you want something along the following example: train <- iris form <- as.formula(paste(names(train)[length(train)], "~ .")) rpart(form, data = iris) or some data.frame method for rpart.... Uwe Ligges
data=train,cp=0.0001) regards & many thanks Christian
