Hello,
I try to make a SVM model using R in Knime. R Learner is okay, but R predictor returns me an error:

I think the problem comes from my dataset because I also tried with the model given in a Knime example but the result is the same.
Using R stand alone I don't have any error.
May anyone help?
Thank you
Nicolas
