Dear Changbin,
that looks odd indeed - can you cast your example in a reproducible one
so I can track this down (or at least send me the data offline?)
Thanks
David

Hi, Dear R community,
IN my data, the out variable is the target variable (0, and 1), hh is
the new data set does not contain the out variable. I trained the model
svm.fit in training data. And want to predict the out in the new data
set hh.
WHy the probabilities are both 0 in 1 and 0 class?
