Hi, I have problem with R Predictor. it shows me only the predictor colum. I have tryied with
- print(confusionMatrix(knime.out, knime.in$target, positive = NULL, dnn = c("Prediction","True")))
but this code produce an Error:
- "'x' must be atomic for 'sort.list'
- Have you called 'sort' on a list?"
does have someone an idea?
'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?
'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?
Hi ramin,
I think the process would be to use first the R Learner Node with something like this:
model <- naiveBayes(Class ~ ., data = ...)
Then, use the R Predictor node to make the prediction:
pred <- predict(model, ...)
In order to visualize the confusion matrix you can use the Scorer node.
As example, I would point you to the Examples Server here: knime://EXAMPLES/07_Scripting/02_R/01_Example_of_R_Snippet
Does this help?
Best,
Vincenzo
