table() reading problem
...ope anyone has an idea of using the table function without this
inconvenience. I thought about writing a counter myself, but that seems
complicated.
Because I have to examine very large examples later on, I don't want to slow
the calculations down if possible.
Thanks for your help in advance.

covariate selection in cox model (counting process)
...umber of observations?
I found several definitions:
AIC= -2 loglik(b) + 2.k
Schwartz Bayesian information criteria:
SBIC= -2 loglik(b) + k ln(n)
Frédérique Letué (author of PhD thesis "COX MODEL: ESTIMATION VIA MODEL
SELECTION AND BIVARIATE SHOCK MODEL",
http://www-lmc.imag.fr/lmc-sms/Frederique.Letue/These3.ps)
suggested me
AIC= - loglik(b) + 2.k/n
BIC= - loglik(b) + 2.ln(n).k/n, with other possible values for parameter
"2" in this case (see her thesis p.100, but this section is in French)
All these do not tell *what to take for n*. There are 3 main possibilities:

"basehaz" in package survival seems to do a cumulative hazard.
extract from the basehaz function:
sfit <- survfit(fit)
