If that's actually what you want to do (which as Frank points out, it
probably isn't), you'll have to do it by hand.
The function step() uses AIC. As far as I know, no-one has yet
constructed valid analogues of AIC,BIC,CIC, ... under complex sampling
(Alastair Scott and I are looking into it), so p-values are the only
option, making the process even less useful.
