Thoughts: Great resource, but scroll to "Eta Squared from Posterior Predictive Distribution"
\(\eta^2\) and Other Effect Size for ANOVA — eta_squared
Functions to compute effect size measures for ANOVAs, such as Eta- (\(\eta\)), Omega- (\(\omega\)) and Epsilon- (\(\epsilon\)) squared, and Cohen's f (or their partialled versions) for ANOVA tables. These indices represent an estimate of how much variance in the response variables is accounted for by the explanatory variable(s). When passing models, effect sizes are computed using the sums of squares obtained from anova(model) which might not always be appropriate. See details.
