[R] Interpreting fa.diagram from package psych

[Ebert,Timothy Aaron]

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.

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
