[R] logistic regression or discriminant analysis ?

[Daniel Amorèse]

Hello,
Does logistic regression really provide better results than lda or qda ?
(my purpose is not classification but highlighting of discriminant
variables).
If this is true, where could I get an R script performing stepwise logistic
regression ?
Thanks
