I would like to perform Cox proportional hazard survival analysis as 
well as logistic regression analysis in R. At this moment I'm using the 
SPSS program to do these analysis (forward or backward conditional, to 
build a model and to obtain the hazard ratios). However, it is unclear 
to me which package and commands I can use to do exactly the same in R? 
For Cox you can used coxph: however, it is unclear how you can do it 
with the forward conditional method?
Is there a way to do it in R? And what with logistic regression?


Best regards,
