What I wanted here was for some way to have a graphical view of a logistic
discrimination, like lda does with plotting discriminant scores. Most non
statisticians find graphical display of results easier to understand. Many
Journals prefer graphics instead of tables to show results.

Apologies for my ignorance. I have never used Logistic discrimination before
and I am still trying to understand some of the concepts.
