I am a new R user (am using it through the Rcmdr package) and have

to find out how to report OR and RR directly when running GLM models
(not
only reporting coefficients.)
Example of the syntax that I have used:
GLM.2 <- glm(diarsev ~ treatmentarm +childage +breastfed,
family=binomial(logit), data=fieldtrials2)
summary(GLM.2)
This works well except that I manually have to calculate the OR
based on the
coefficients. Can I get these directly (with confidence intervals)
by just
amending the syntax?
Look at predict.glm {stats}. It gives both facilities and the help
page looks very clear.
