[R] reference for logistic regression

[darteta001 at ikasle.ehu.es]

Dear list, first accept my apologies for asking a non-R question.

Can anyone point me to a good reference on logistic regression? web or 
book references would be great. I am interested in the use and 
interpretation of dummy variables and prediction models.
I checked the contributed section in the CRAN homepage but could not 
find anything (Julian Faraway´s "practical Regression and ANOVA using 
R" does not cover logistic regression)

Thanks for your help,

David
