Re: [R] Classifying boolean values

Yes, it works! Thanks a lot! Now, i have another question... When i try to use the tree for predict the value of the class with the function "predict" the result is not a vector with TRUE or FALSE value (that is what i want for every row of my test set) but is a sort of matrix with a weight on the

Re: [R] Classifying boolean values

It's likely that class is numeric and you actually want factor (regression tree vs classification tree). str(echoknn.train) will show you. By saying, "I have to build a tree classifier" you make me think that this is a course assignment. If it is, you should perhaps talk to your instructor. If no

[R] Classifying boolean values

Hi to all, I'm new to this forum and new to R. I have to build a tree classifier that has boolean values as response. When I build the tree with: echoknn.tree <- tree(class ~ ., data=echoknn.train) where "class" is a coloumn of my dataset (echoknn.train) of boolean values, the result is a tree wh
