[R] plot(cox.zph()): customize xlab & ylab

[Adaikalavan Ramasamy]

Duncan, your solution could be simplified using ann=FALSE in the plot

 fit <- coxph( Surv(futime, fustat) ~ age + rx, ovarian)
 plot( cox.zph(fit), ann=F )
 title( xlab="My own label", ylab="A new label", main="A clever title")

Now, why did I not think of this before ?

Regards, Adai
