Hello. I am using the aovp() function from the library lmPerm with one factor (group: 3 levels) controlling for 2 covariates. I now want to conduct a post-hoc test using the same model. Unfortunately, I did not find an appropriate test which works with 2 covariates. I would be grateful for any suggestions. Thank you.
