cal.window

Calendar time cut of survival data

For a given time interval, each spell is cut so that it fully lies in the given time interval

cal.window(dat, window, surv = c("enter", "exit", "event", "birthdate"))

`dat`	Input data frame. Must contain survival data and a birth date.
`window`	Vector of length two; the time interval
`surv`	Vector of length four giving the names of the central variables in 'dat'.

The window must be in the order (begin, end)

A data frame of the same form as the input data frame, but 'cut' as desired. Intervals exceeding window[2] will be given event = 0
