In andr3wli/powerPsych: Effect Size and Power Toolbox for Psychologists

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

Here I present cohens_plot as a friend for cohens_d. This function is to help aid the interpretation of Cohen's d statistic. This is a really useful function for users to be able visualize the overlap of groups. Simply type in 2 means and 2 standard deviations and a plot will be generated to show the overlap. The default is set so that the over lap is shaded but if you want, you can set overlap = F for no overlap.

The ggplot2package is used under the hood to produce the plots. theme_void() is used to produce the minimalist plot.

To produce a plot, simply fill in 4 arguments. Note that overlap is set as the default. You can set it to false for a plot without overlap

library(powerPsych)
cohens_plot(0, 1, 0.5, 0.5)

To produce a plot without any overlap:

cohens_plot(0, 1, 0.5, 0.5, overlap = F)
