In R, I see support for ARCH models and for ARMA models (in the
tseries package). How would we estimate the workhorse model where
stock returns are ARMA with ARCH errors?

I am aware of the paper by Andy Weiss. I have used this model quite a
bit using stata and consider it a staple. I couldn't find mention of
it in the tseries library.
