plot_joint_circ {cylcop}

Circular Scatterplot of Turn Angles and Step Lengths

Description

This function produces a circular scatterplot with the step lengths plotted as distance from the center of a circle and the turn angles as angles (polar coordinates).

Usage

plot_joint_circ(traj = NULL, theta = NULL, x = NULL)

Arguments

traj

data.frame containing the trajectory produced by e.g. traj_sim(). It must contain the columns traj$angle and traj$steplength.

theta

(alternatively) numeric vector of angles (measurements of a circular variable) or "circular" component of pseudo-observations.

x

(alternatively) numeric vector of step lengths (measurements of a linear variable) or "linear" component of pseudo-observations.

Details

You can either specify traj or the angels and step lengths theta and x.

Value

A 'ggplot' object.
