Stop the time of an event history object
All event times are stopped at a given time point and corresponding events are censored
stopTime(object, stop.time)
object |
Event history object as obtained with |
stop.time |
Time point at which to stop the event history object |
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.
