R help - Sep 2022 - Interpreting fa.diagram from package psych

Sorry, the file was automatically downloaded and opened with the
browser instead of pointing to the webpage.
Here is a better link:
https://cran.r-project.org/web/packages/psychTools/vignettes/factor.pdf
The figure is on page 22.
The question is: The dots have different colors; how do I know what
they represent?
Is there a way to show an auto-legend?
Thank you

It is a bad graphic as the legend that should explain the color coding is
missing. The next option is to copy the data and code and see if you can
reproduce the figure. You can then play with the code and read a bit about the
procedures to figure out what is going on. It should not be too hard. My guess
is that there is some additional variable with three states that is being used.
If this were the iris data set I would guess it was the three species: setosa,
versicolor, and virginica.
