You can do this directly with the survfit function (survival verstion 2.37 or greater)
If status is a factor variable with levels of censored, relapse and death
fit <- survfit(Surv(time, status) ~ sex, data=mydata)
The primary advantage of this over the cuminc package is that all of the usual options for
survival plots carry forward.
