Usage

extract_event_segments(x, eventID, lead_secs = 0L, lag_secs = 0L)

Arguments

x

list from detect_proximity_events(); contains $data and $events

eventID

character(1). Event identifier to extract

lead_secs

integer(1). Seconds to extend window before event start (>=0)

lag_secs

integer(1). Seconds to extend window after event end (>=0)

Value

• animal: track_tbl

• vessel: track_tbl

• meta: list with event metadata and window bounds
