If possible, I would find it very useful if glm.nb (from the Mass package) was added to caret

Kind regards

Give that a try. It tunes over the link function and, for my test cases, the identity link may produce errors (since the predictions are not constrained to be non-negative). Using tuneLength = 1 will only evaluate the log link.
