When using cohen.d(), the factor level order no longer allows you to dictate which group set comes first. This causes the direction of cohen's d to be off depending on the situation.
Is there any way to input what level you want as group 1 vs 2 to ensure the direction of the effect size is correct, such as in time series data?
