I apply Repeated measures ANOVA for analyzing ERPs data. To do this I
use lme() function and glht() for the post hoc analysis.
I followed the very useful suggestions found in this help list but I
have a problem. I do not know how to test the interaction between
different levels of my predictors.
Consider I have 2 predictors, the first one has three levels: A,B,C;
also the second one has three levels:1,2,3. How can I investigate, for
example, the interaction between A and 2?
Thank you in advance for your help.
