If the documentation for those models does not tell you how, then you should ask yourself whether what you are trying to do makes sense statistically. The question of what makes sense statistically is not a good fit for this forum, which is about R.
By the way, root mean square errors are easy to calculate... the hard part is knowing whether doing so is informative per above. -- Sent from my phone. Please excuse my brevity.
