Here is some sample code. It generates a class (list_var) that is used in
rpart. list_val is the dependant variable.
The plot shows all the values of the class, which is a mess and makes the
plot unuseable. I'd like to either suppress the list entirely or replace it
with something like "Group 1
I have a class with 732 members, so using rpart.plot is giving me a tiny plot
in the middle of the window. Is there a good way to modify the plot, or
replace the long list with something like "group1"?
