Bagged Trees Prediction Dear Dr. Ballings,
I spoke to you about this in office hours.
I ran this code to create one bagged tree:
tree <- rpart(yTRAIN ~ ., BasetableTRAIN)
predTREE <- predict(tree,BasetableTEST,type="prob")[,2]
I got this error message:
Error in predict.rpart(tree, BasetableTEST, type = "prob") :
Invalid prediction for "rpart" object
How would you suggest fixing this problem?
Thanks for your help.
Answers and follow-up questions Answer or follow-up question 1
Is yTRAIN a factor?
Can you show me the output of str(output)?
