One possible solution is to calculate ANOVA by using the function aov and then use the function TukeyHSD for calculating pairwise comparisons: anova_df = aov (RT ~ side*color, data = df) TukeyHSD (anova_df) The downside is that the calculation is then limited to the Tukey method, which might not always be appropriate.
