[R] poisson with overdispersion

[Amanda Phipps]

I am fitting a poisson model and it appears to have
overdispersion.  I am interested in using the
quasipoisson family (with the glm command).  Will this
account for the overdispersion in the model?  Is there
an additional method for accounting for a dispersion
parameter not equal to 1 (with the glm command)?  

And after fitting the model, how to I obtain the
fitted values and their respective standard errors?

Thank you-
