[R] [newbie] Cox Baseline Hazard

[Meles MELES]

Hello everybody.
First of all, I would like to present myself.
I'm a french student in public health and I like statistics though I'm 
not that good in mathematics (but I try to catch up). I've discovered R 
recently while trying to find a statistical program in order to avoid 
rebooting my computer under windows when I need to do some statistical 
work.

And here is my first question.
I'm actually trying to model a survival curve using a cox model.
But I need the baseline cumulative hazard. I've been looking around on 
the web and the archives, and I found that it as to do with the 
nelson-aalen estimation.
But I must not understand all the doc very well, because I can't get 
the baseline hazard.
Could you help me, please.

Best regards.

PS : I hope you'll forgive my poor english writing.
