Coxph with factors
...DATA<-data.frame(time.sec,done,f.pom=factor(f.pom),po,vo)
> final<-coxph(Surv(time.sec,done)~f.pom*vo+po,data=DATA)
> final.surv<-survfit((final), individual=T,conf.type="log-log")
> print(final.surv)
Also, when I trying using survfit with presepecified values for the
covariates and factor (i.e. '0' to get the baseline) I get an error message,
which I think is a result of my inability to specify the factors in the
correct manner.
I would very much appreciate if somebody can help me out.
Thanks very much,
Kylie
