Arguments

enter	Left truncation time point.
exit	End time point, an event or a right censoring.
event	Event indicator.
strict	If TRUE, then tabulating is not done after a time point where all individuals in a riskset failed.

events	Number of events at each event time point.
riskset.sizes	Number at risk at each event time point.
