[R] External regressors in GARCH

Hello to all R users,

up to my knowledge, neither garch(tseries) nor garchFit(fGarch) support including external regressors in the regression, which, for example, arima(stats) can do by setting xreg. Is there a package or any other way that can do this?

To be precise, I want to estimate a variance equation that goes like this: h_t = arch_t + garch_t + dummy1_t + dummy2_t + v_t.

Any advise appreciated!
