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?
