[R-sig-finance] Generalized Method of Moments package for R?

[Gray Calhoun]

Hi,
  Are there R packages for Generalized Method of Moments?  I've
searched the help archives and help files without coming across
anything that looked appropriate, but I may have overlooked something.
 I know that there is Matlab software to do GMM, but I'm using Windows
so (I think) I can't use RMatlab.  I'd appreciate any suggestions
anyone might have.

Thanks,
Gray
