[S] confidence interval for fitted values with gee

Dear S+ users,

I posted this message a few days ago but did not get any answer.

How can I get confidence intervals for the fitted values obtained from
generalised estimating equations programs ?

I am using the gee() function implemented in the Oswald library
(http://www.maths.lancs.ac.uk/~smithdm1/Oswald/). I tried the usual tools
(predict.lm(), predict.glm(), predict.gam(), pointwise()), but the
corresponding methods have not been implemented for gee objects.

I am working with S-Plus 4.5 / Win95.

Please tell me if this question is dumb (and if yes, why !).

Thanks in advance,

Renaud
