speed2bearing: Compute the bearing of a speed vector

In Rafnuss/GeoPressureR: Global Positioning by Atmospheric Pressure

Compute the bearing of a speed vector

Description

This function convert a speed vector represented in complex number into a bearing angle (0°=N ; 90°=E...). This conversion is needed because trigonometric angle are different than bearing.

Usage

speed2bearing(
  speed,
  speed_ref = complex(real = 0, imaginary = 1),
  positive = TRUE
)

Arguments

speed	speed as complex value
speed_ref	reference vector of the angle. Default is the North in order to return bearing. Use speed_ref = 1 for trigonometric orientation (clockwise from East).
positive	logical to ensure the bearing is positive between 0-360 degree.

Value

bearing angle in degree
