split: Splitting a MoveStack

In move: Visualizing and Analyzing Animal Track Data

Description

Splitting MoveStack in a list of Move objects

Usage

  ## S4 method for signature 'MoveStack,missing'
split(x, f, drop=FALSE, ...)

Arguments

x	MoveStack or MoveBurst object
f	not needed
drop	not needed
...	not needed

Details

A MoveStack is split into a list of Move objects by the track IDs of the given MoveStack. For stacking moveStack can be used. Also a MoveBurst object can be split this will lead to seperate list elements for every burst, every location where the burst is switched will then be recycled.
