Mag: Magnitude and angle of a vector

In metR: Tools for Easier Analysis of Meteorological Fields

Magnitude and angle of a vector

Description

Computes the magnitude of a vector of any dimension. Or angle (in degrees) in 2 dimensions.

Usage

Mag(...)

Angle(x, y)

Arguments

...	numeric vectors of coordinates or list of coordinates
x, y	x and y directions of the vector

Details

Helpful to save keystrokes and gain readability when computing wind (or any other vector quantity) magnitude.

Value

Mag: A numeric vector the same length as each element of ... that is \sqrt(x^2 + y^2 + ...). Angle: A numeric vector of the same length as x and y that is atan2(y, x)*180/pi.
