[R] Working with FactoMineR

[Bill Dunlap]

This will happen if you select no points when it asks you to 'click on
the graph' (to select the level at which to cut the tree).  On Windows
you can select no points by right clicking and selecting 'Stop' from
the menu that pops up.  RStudio may have a different way to select no
points.
