No, there is no built-in function for that. "accuracy" is not well-enough defined in the situation for there to be a function for that.
If rms() does not do the job for you, you should probably looking at precision or recall rather than some not-defined accuracy .

You can use loss function to predict classes for the test data and to get accuracy of prediction.
