Magnitude and angle of a vector

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

Mag(...)

Angle(x, y)

Arguments

...

numeric vectors of coordinates or list of coordinates

x, y,

x and y directions of the vector

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.

Details

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