pwr2ppl contains protocols for running a wide range of power analyses. Analyses range from simple approaches such as t-test and correlations to multifactor ANOVA (between and within subjects, linear mixed model approaches) and regression-based approaches (basic multiple regression, moderated regression, mediation, and logistic regression). Recent additional focus on improving mediation approaches through addition of joint signficance tests and conditional process models.
These protocols accompany the book Applied Power Analysis for the Behavioral Sciences (2nd ed.)
The book gives lots of illustrative examples of using the code but is not necessary for using the package.
I built this under R 4.2.0
