Source: R/event_azimuth.R
event_azimuth.Rd

This function measures the azimuth between two events. It returns a vector of azimuths of the same length as the number of events in x, with the azimuth for the last event of each track padded with an NA.

Usage

event_azimuth(x, units)

Arguments

x

A move2 object

units

Optional, the units to use for the azimuth (e.g., "degrees" or "radians"). The default is "degrees".

Value

a vector of azimuths of the same length as the number of events in x, with the last value set to NA for each track.
