Hello everyone,

I tried to use coxph.detail() to get the hazard function.  But a warning
messge always returns to me, even in the example provided by its help

> ?coxph.detail
> fit   <- coxph(Surv(futime,fustat) ~ age + rx + ecog.ps, ovarian, x=TRUE)
> fitd  <- coxph.detail(fit)
Warning message:
data length [37] is not a sub-multiple or multiple of the number of
rows [12] in matrix

Can anyone suggest why it does not work?

I use R 2.1.1 with Windows XP

Thanks a lot.

Zhen Zhang
