fert2 <- fert[fert$parity == 2, ] fit <- coxreg(Surv(next.ivl, event) ~ ses + age + year + parish, data = fert2) prop.full <- cox.zph(fit)

Error in cox.zph(fit) : unexpected assign component

Dear Wahid,

cox.zph is a function from the survival package, so to get what you want, try

fit <- survival::coxph(....) prop.full <- survival::cox.zph(fit)

and you should be fine.

Best, Göran

I have loaded the survival and eha packages.

I don't have a problem with coxph, just cox.zph

the error message is...

Error in cox.zph(fit) : unexpected assign component

Still after my suggestion, i.e.

fit <- coxph(...) cox.zph(fit)

?

Then you should ask the maintainer of 'survival', not me.
