Dear Charles, see the help file and the examples at http://cran.r-project.org/web/packages/fGarch/fGarch.pdf or use ?garchFit
in the examples you will see for example: garchFit(~ garch(1,1), data = x.vec, trace = FALSE) Try something like that. Make sure you provide the package of the function next time!
