interpPath: Interpolate trajectory into points

In aspillaga/fishtrack3d: Analysis of Passive Acoustic Telemetry Data in 3D

Description

This function takes a single trajectory and interpolates it into a set of points that are spaced by a given time step. If a maximum time lag is provided, the function will not interpolate segments between locations that are separated by more than the maximum lag.

Usage

interpPath(path, time.step = 2, max.lag = NULL)

Arguments

path	a data.frame with the trajectory of a individual. It must contain the time.stamp, x, y and depth columns.
time.step	time interval into which interpolate the trajectory, in minutes.
max.lag	maximum time period, in hours, above which the trajectory between two locations will not be interpolated.

Value

a data.frame with the resulting interpolated locations.
