[R] Robust Standard Errors for lme object

I have fitted a linear mixed model using the lme function but now wish to
calculate robust standard errors for my model.  I have been able to find
several functions which calculate robust s.e for lm objects but have not been
able to find a function which calcualtes robust s.e for lme objects.  Would
anyone know of a function that will allow me to do this.

Many Thanks
