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
Hi Dennis,
look at the help page for summary.survfit, the Value n.event.

I have created objects using the Surv function in the survival package:
FIT.1
Call: survfit(formula = FORMULA1)
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"]
