coxph.detail() does not work
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
document:
> ?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
