[R] logistic regression based on principle component analysis

[江文恺]

Dear all:

I try to analyse a dataset which contain one binary response variable and serveral predict variables, but multiple colinear problem exists in my dataset, some paper suggest that logistic regression for principle components is suit for these noise data,
but i only find R can done principle component regression using "pls" package, 
is there any package that can do the task i need - logistic regression based on principle components,
if not, can anyone give some suggestion about how to use R to do my work.
Thanks very much!
best regards!
