EDIT 2022-01-17: to make seamless with jonathon-love/jsq, changing all instances of jaspGraphs to JASPgraphs (reversing name change from 2020 in jasp-stats repos)

For almost all plots, the idea is that you only use two functions of JASPgraphs: geom_rangeframe(), and themeJaspRaw().

Assuming you created some ggplot2 object called plot, you can do:

plot +
  JASPgraphs::geom_rangeframe() + # add lines on the x-axis and y-axis
  JASPgraphs::themeJaspRaw()      # add the JASP theme

JASPgraphs is only available through GitHub, so you need to use some package that supports that (e.g., remotes, renv, pak, etc.)

remotes::install_github("k-motwani/JASPgraphs")
