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.

The repeated-measures ANOVA is used for analyzing data where same subjects are measured more than once. WebI'm aware of multivariate approaches to repeated measures ANOVA in R, but my first instinct is to proceed with a simple aov () style of ANOVA: aov.repeated <- aov (DV ~ IV1 * IV2 * Time + Error (Subject/Time), data=data) DV = response variable. However, we cannot use this kind of covariance structure To find how much of each cell is due to the interaction, you look at how far the cell mean is from this expected value.
