Subject: Running effect size tests on subsets of data
Hello all,
I have seen instructions for conducting post-hoc pairwise comparisons in R after running an ANOVA, Kruskal-Wallis Test, or Yuen?s Test.
Is there a method to subset data automatically to run an effect size test across different pairs? For example, if I want to run Cohen?s d to examine the differences in data between different days of the week. My X variables would be the pairs below. (Note that no data was collected on Saturday.) I can subset the data manually and apply the effect size to each pair. Is there a way in R to create the pairs and run the effect size test all at once?

Any assistance you can provide would be much appreciated.
