R help - Nov 2018 - How to add a dummy code for (G)LMER

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

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.
