I want to conduct post hoc comparisons for a model with a three-way interaction:
FullModel <- lmer(CIVADmc ~ 1 + Factor1 * Factor2 * Factor3 + (1|ID) + (1 | Item), data=EXP3)
I tried the following, but this does not work.
summary(glht(FullModel, linfct = mcp(Factor1*Factor2*Factor3 = "Tukey")), test = adjusted("holm”))
any suggestions?
