Dear R experts -- I never needed to add a dummy column and always query statistical results by querying summary(model) for GLMER. However, I was recently asked to add a dummy column for interaction variables when performing GLMER. Could anyone tell me if it's necessary to add a dummy column for GLMER or R automatically handles it when outputting results? Best, Yune
How to add a dummy code for (G)LMER

I am almost certain that no dummy variables are necessary -- but mixed models questions are always better posed on the r-sig-mixed-models list. Bert
