Time-point by which a specified number of events occurred.

This returns the study time-point by which a specified number of events (PFS or OS) occurred.

getTimePoint(data, eventNum, typeEvent, byArm = FALSE)

Arguments

data: (data.frame)
illness-death data set in 1rowPatient format.
eventNum: (int)
number of events.
typeEvent: (string)
type of event. Possible values are PFS and OS.
byArm: (logical)
if TRUE time-point per treatment arm, else joint evaluation of treatment arms.

Value

This returns the time-point by which eventNum of typeEvent-events occurred.
