perIdVels

This function calculates headings and speeds based on
consecutive locations of 1 individual. Based on the <code>heading</code> and the
<code>linear_speed</code> functions of <code>swaRm</code>.

internal

Provides a pipeline for the comparative analysis of
collective movement data (e.g. fish schools, bird flocks, baboon troops) by
processing 2-dimensional positional data (x,y,t) from GPS trackers or computer
vision tracking systems, discretizing events of collective motion, calculating
a set of established metrics that characterize each event, and placing the
events in a multi-dimensional swarm space constructed from these metrics.
The swarm space concept, the metrics and data sets included are described in:
