Dividing two RooFit functions


I have two distributions which I fit using two user-defined RooGenericPdf s.

Now, I would like to plot the ratio of these two fit functions with error bars. Is there a way to do this using RooFit?

Is there an equivalent to TF1 Eval(xx)? Is there a way to store or bind the RooGenericPdf as a TF1?

Thanks for the help.
