I have a lmer model with two within factors
lmer (variable ~ time * condition + (1|id), data= df)
time having 2 levels (
condition having 2 levels (
The coefficient estimation computes parameters for:
cond2 cond2:post post
How does R take the reference term to compare the level?
How can I get the other interactions between
cond:time? If I run a model with a 3 levels fixed effect, it always misses some interactions. It seems that generate only comparison with the reference term and not among the other levels of a fixed effect.
