good afternoon! I have problem with a decisional trees.
f11<-as.factor(Z24train$f1) fit_f1 <- rpart(f11~TSU+TSL+TW+TP,data = Z24train,method="class") plot(fit_f1, uniform=TRUE, main="Classification Tree for Kyphosis")
But this error appears:
Error in plot.rpart(fit_f1, uniform = TRUE, main = "Classification Tree for Kyphosis") : fit is not a tree, just a root
which is the problem? thanks for the help 🙂
