R help - Mar 2011 - Garchoxfit package

Dear List,
I'm now using Ubuntu 10.10 and I want to use the garchoxfit
function.It seems that I need to download the package.

While after installing the package,I still can't use the garchoxfit
function.What's the reason and how to fix that?

Thanks for your time!

Best,
Ning

A typical beginner error is to forget to also use either library() or  
require() to load an installed package. Installation only puts the  
files in the library. It does not load it into the workspace. You  
should in the future offer your session which will make comments more  
specific than this guessing game you have requested.

Dear Ning,

are you referring to the deprecated function garchOxFit() of the package fGarch,
formerly contained in fSeries? If so:

library(sos)
findFn("garchOxFit")

which yields:

	http://finzi.psych.upenn.edu/R/library/fGarch/html/00fGarch-package.html

And there you will find at the bottom of the page:

OX Interface

NOTE: garchOxFit is no longer part of fGarch package. If you are interested to
use, please contact us.

contains a Windows interface to OX. 

The function garchOxFit interfaces a subset of the functionality of the G at
ARCH 4.0 Package written in Ox. G at RCH 4.0 is one of the most sophisticated
packages for modelling univariate GARCH processes including GARCH, EGARCH, GJR,
APARCH, IGARCH, FIGARCH, FIEGARCH, FIAPARCH and HYGARCH models. Parameters can
be estimated by approximate (Quasi-) maximum likelihood methods under four
assumptions: normal, Student-t, GED or skewed Student-t errors.

Furthermore, do you have Ox installed on your PC?
