Hi
I read the famd method described at http://www.sthda.com/english/articles/31-principal-component-methods-in-r-practical-guide/115-famd-factor-analysis-of-mixed-data-in-r-essentials/ however, when I try to run the following commands, I am not able to get the coordinates of the categorical variables (Label and Soil).

What should I use to see the coordinates of Label and Soil?
