Hi all,
I am very grateful to all those who write to me
1) how i  can  obtain relative risk (risk ratio) in logistic regression in R.

           estimators, and algorithms},
   number = 293,
   institution = {{UW} Biostatistics Working Paper Series},
   keywords = {glm, Poisson},
   url = {http://www.bepress.com/uwbiostat/paper293}

2) how to obtain  the predicted risk for a certain individual using
fitted regression model in R.

Many thanks, in advance, for your help.
