trip (version 1.1-21)

trackAngle: Determine internal angles along a track

Description

Calculate the angles between subsequent 2-D coordinates using Great Circle distance (spherical) methods.

Usage

trackAngle(x)


"trackAngle"(x)


"trackAngle"(x)

Arguments

x
trip object, or matrix of 2-columns, with x/y coordinates

Value

Vector of angles (degrees) between coordinates.

Details

If x is a trip object, the return result has an extra element for the start and end point of each individual trip, with value NA.

This is an optimized hybrid of "raster::bearing" and gzAzimuth.
