[R-sig-ME] Multiple comparisons with interaction

[Mayara Amescua]

Hi everyone,

I'd like to do a multiple comparisons for a interaction between variables
and I tried to
create a new variable to use in the glmer model.

rec.mês<-interaction(aag$rec,aag$mês,data=aag,drop=TRUE)

But I got this message. I've tried to follow some texthelpers but
nothing worked.

Error in sort.list(y) : 'x' must be atomic for 'sort.list'

Have you called 'sort' on a list?

Does someone could help me how to solve it?

Let me know if you need more information.

Thanks,

Mayara
