After reading about interactions contrasts in emmeans, I just wanted to make sure I understood it correctly. Say I have a model with a group*time interaction effect, and I set up emmeans as follows:
emm <- emmeans(lme, ~ Group * Session)
And then use
contrast(emm, interaction = TRUE, "pairwise", adjust="mvt")
It outputs something like
Group_pairwise Session_pairwise estimate SE df t.ratio p.value
Group_A - Group_B Session1 - Session2 x.xxx x.xxxx xx.x x.xxx 0.001
Group_A - Group_B Session1 - Session3 ...
...
Does the first line for example then say that the difference between Session 1 and 2 within Group_A is significantly different to the difference between Session 1 and 2 within Group_B?
So it is basically a contrast of contrasts?
contrast(emm, interaction = "pairwise")
