deviation_norm {tectonicr}

Normalize Angle Between Two Directions

Description

Normalizes the angle between two directions to the acute angle in between, i.e. angles between 0 and 90^\circ

Usage

deviation_norm(x, y = NULL)

Arguments

x, y

Minuend and subtrahend. Both numeric vectors of angles in degrees. If y is missing, it treats x as difference. If not, length of subtrahend y is either 1 or equal to length(x).

Value

numeric vector, acute angles between two directions, i.e. values between 0 and 90^\circ
