R help - Jan 2006 - Odds Ratios in Logistic Regression with Effect Modifiers

Hi R Users...

I'm trying to get the Odds Ratios for Logistic Regression Coefficients and
their confidence intervals when there are interactions, or effect modifiers, in
the regression model. May anyone help me how to get them?

Thanks
