Re: [R] Extracting values from Surv function in survival package

I don't think that gives the summary of event numbers without extra work. library(survival) fit <- survfit( Surv(time,status)~sex,data=lung) summary(fit)$n.event [1] 3 1 2 1 1 1 1 2 1 1 1 2 1 1 2 1 1 1 1 1 1 1 1 1 2 1 1 1 1 2 3 1 1 1 1 1 2 [38] 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

Re: [R] Extracting values from Surv function in survival package

More difficult than it should be IMO. survminer package is often helpful. But if you want to avoid dependency: library(survival) fit <- survfit( Surv(time,status)~sex,data=lung) surfable <-summary(fit)$table surfable # just the events surfable[,"events"] On Wed, 15 May 2024, 21:42 Dennis Fishe
