traj_get: Get a Trajectory from Coordinates

In cylcop: Circular-Linear Copulas with Angular Symmetry for Movement Data

Get a Trajectory from Coordinates

Description

The function calculates step lengths and turn angles from x- and y-coordinates and calculates pseudo-observations from those step lengths and turn angles.

Usage

traj_get(x_coords, y_coords)

Arguments

x_coords	vector of numeric values containing the x-coordinates of a trajectory.
y_coords	vector of numeric values containing the y-coordinates of a trajectory.

Value

A data.frame containing the trajectory. It has 6 columns containing the x and y coordinates, the turn angles, the step lengths, and the pseudo-observations.

Examples

set.seed(123)

traj <- traj_sim(n = 5,
copula = cyl_quadsec(0.1),
marginal_circ = list(name="vonmises",coef=list(0, 1)),
marginal_lin = list(name="weibull",coef=list(shape=3))
)

traj_from_coords <- traj_get(traj[,1], traj[,2])
