ChangeObservationWindow.e: Changes observation window to period between two transitions

In Biograph: Explore Life Histories

Description

Observation starts at time of entry into given state (entrystate) and ends at time of entry into another given state (exitstate). If exitstate = NULL, then observation ends at last date for which data are available. Entry into entrystate and entry into exitstate must lie in original observation window.

Usage

ChangeObservationWindow.e(Bdata, entrystate, exitstate)

Arguments

Bdata	Biograph object
entrystate	Observation starts at time of entry into entry state
exitstate	Entry into exitstate implies end of observation. If exitstate = NA, observation ends at end of initial observation window

Value

Biograph object with information on new observation window and transitions during the new observation window.
