Interaction() has no data argument. Try interaction(aag$rec, aag$m?s, drop = TRUE) or with(aag(interaction(rec, m?s, 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.

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.

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.m?s<-interaction(aag$rec,aag$m?s,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
