R help - Feb 2007 - Fitting Weighted Estimating Equations

Hello Everybody:
 
I am searching for an R package for fitting Generalized Estimating Equations
(GEE) with weights (i.e. Weighted Estimating Equations). From the R
documentation I found "geese(geepack)" for fitting Generalized
Estimating Equations. In this documentation, under the paragraph “weights” it
has been written, “an optional vector of weights to be used in the fitting
process. The length of weights should be the same as the number of observations.
This weights is not (yet) the weight as in sas proc genmod, and hence is not
recommended to use.” Now my question is, is there any other package you know
that might allow me to fit GEE with weight option and the results would be same
as SAS PROC GENMOD with weights? Any help would be sincerely appreciated.
 
Thank you very much. 
 
Sincerely,

The `yags' function in the `yags' package (available from Prof
Ripley's
CRAN extras) has got a `weights' argument, though I've never used it and
I've got no idea whether it corresponds to GENMOD's weights statement.
