Interaction() has no data argument. Try interaction(aag$rec, aag$mês, drop = TRUE) \
or with(aag(interaction(rec, mês, drop = TRUE))

To call in the statistician after the experiment is done may be no more than asking \
him to perform a post-mortem examination: he may be able to say what the experiment \
died of. ~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not ensure that \
a reasonable answer can be extracted from a given body of data. ~ John Tukey

Onderwerp: [R-sig-ME] Multiple comparisons with interaction

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
