I am using SVM to classify categorical data and I would like the
probabilities instead of the classification. ?predict.svm says that its
only enabled when you train the model with it enabled, so I did that, but it
didn't work. I can't even get it to work with iris. The help file shows
that probability = TRUE when training the model, but doesn't show an
example. Then I try to predict with probabilities, I still only get
classifications back. Anyone get this to work and can help me out?

Thanks,

Roger
