Movement metrics

Description

Functions to calculate metrics such as straightness, mean squared displacement (msd), intensity use, sinuosity, mean turn angle correlation (tac) of a track.

Usage

straightness(x, ...)

cum_dist(x, ...)

tot_dist(x, ...)

msd(x, ...)

intensity_use(x, ...)

sinuosity(x, ...)

tac(x, ...)

Arguments

x

[track_xy, track_xyt]
A track created with make_track.

...

Further arguments, none implemented.

Details

The intensity use is calculated by dividing the total movement distance (tot_dist) by the square of the area of movement (= minimum convex polygon 100).

Value

A numeric vector of length one.
