R help - May 2007 - Problem with GARCH models in R compared to S-PLUS

Hi R,

 I have three queries regarding handling GARCH functions in R. Below I
document the same:



Unlike S-Plus, R doesn't handle Multivariate GARCH models.
R has a package for BEKK GARCH model but not for DVEC GARCH models.
The GARCH function in S-PLUS has the capability of fixing some model
parameters at certain values to evaluate the fit of a particular model. But
the same optionality is not provided by the GARCH models in R.


So, how can I overcome these difficulties which I am facing in R? Are these
procedures in the development stage of R? (I mean the packages are yet to be
built?)..Any developmental work going on with this?

Thank a lot for your help,

Shubha
