[R] a more specific question about qda

Perhaps, I should complement my previous e-mail question:
I am trying to select variables through a quadratic discriminant analysis.
It seems to me that a robust criterion is the value of the discriminatory
power
(i.e. the ratio of the separation of the class means to within-class
variance)
How can I obtain this ratio from V & R's qda() output ?
Thanks
(I hope this question is relevant)
