Adjusted Rate Ratios in R

Wed, May 25, 2011 5:49 AM #

I am trying to calculate Poisson regression based adjusted rate ratios in R,
but R's default in glm does not code the intercept as the global rate.  In
SAS I use "cell means" coding so that the intercept is the global rate, but
I do not know how to do this in R.  If anyone knows a way to make glm use
"cell means", or an how to find adjusted rate ratios I would be grateful.
