stopTime(object, stop.time)

Arguments

object

Event history object as obtained with Hist

stop.time

Time point at which to stop the event history object

Value

Stopped event history object where all times are censored at stop.time. All observations with times greater than stop.time are set to stop.time and the event status is set to attr(object,"cens.code"). A new column "stop.time" is equal to 1 for stopped observations and equal to 0 for the other observations.

set.seed(29)
d <- SimSurv(10)
h <- with(d,Hist(time,status))
h
stopTime(h,8)
stopTime(h,5)

## works also with Surv objects
library(survival)
s <- with(d,Surv(time,status))
stopTime(s,5)

## competing risks
set.seed(29)
dr <- SimCompRisk(10)
hr <- with(dr,Hist(time,event))
hr
stopTime(hr,8)
stopTime(hr,5)
