R help - Aug 2007 - using sampling weights in glm

Hi,

I have a supposedly representative sample from a
stratified survey. Hence, all observations have an
associated sample weight each which inflate the sample
to population size. 

I want to run a glm probit regression on the data but
I am not clear about if or better how I can use the
weights in it. From the description of the weights
argument of glm it seems to me that I cannot plug
these weights in there.

Has anybody some advice for me?

Many thanks,
  Werner

You want svyglm() in the survey package.
