The supported models are restircted to those listed in the help page.
For the family of GARCH models these are in its moste general form

    ARMA(m,n)-APARCH(p,q).

I have not considered to add regression.

Hello, R people:

    I have a question in using fSeries package--the funciton garchFit and
garchOxFit
 if adding a regression to the  mean formula, how to estimate the model in
R? using garchFit or garchOxFit?
  For example, Observations is {x,y}_t,there may be some relation between x
and y.
  the model is
   y_t=gamma0 + *gamma1*x_t*+psi*e_{t-1}+e_t       the gamma1*x_t is
regression.
   e_t=sqrt(h_t)*N(0,1)
   h_t=alpha0+alpha1*e_t^2+beta*h_{t_1}~~~~~~~GARCH(1,1).
   I  didn't know how to estimate the model using function garchFit or
garchOxFit or other functions?    because the argument in
garchFit/garchOxFit is formular.mean=~arma(1,1).

  Do you have some instrucitons?
  thank you very much for you help.

Best wishes

Ma Yuchao
