[R-SIG-Finance] using garchFit function

[fernando]

I want to fit an AR-GARCH model with garchFit. 
On the arma specification I need only the AR(8).
But the code
fit <- garchFit(~arma(8,0), ~garch(1,1), cond.dist="dstd")
give all the AR's terms until the AR(8).
Any help with is issue. Thanks a lot
fernando
