conPhase: Process contact phases

In wildlifeDI: Calculate Indices of Dynamic Interaction for Wildlife Tracking Data

Process contact phases

Description

Computes phases where contacts occur based on a temporal tolerance.

Usage

conPhase(ltraj, pc = 0, idcol = "burst")

Arguments

ltraj	an object of the class ltraj which is output from the function conProcess.
pc	time (in seconds) to allow for which to combine contact events (see details).
idcol	column used to identify individuals (default is the burst)

Details

This function is used following the conProcess function to arrange contacts into phases where continuous contact occurs (based on the user-defined time threshold pc. The idea is that we can consider a phase to be a continuous contact event (based on dc see conProcess) as long as the contact is only interrupted for no more than pc time units.

Value

An ltraj object with new column contact_pha.
