jaspGraphs contains selective functions that extend ggplot2 for creating plots for JASP.

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("jasp-stats/jaspGraphs")
