Compute an angle in 3D space

Description

Compute an angle in 3D space

Usage

get_3d_angle(x1, y1, z1, x2, y2, z2, x3, y3, z3)

Arguments

x1	x-coordinate of first point
y1	y-coordinate of first point
z1	z-coordinate of first point
x2	x-coordinate of second point (vertex)
y2	y-coordinate of second point (vertex)
z2	y-coordinate of second point (vertex)
x3	x-coordinate of third point
y3	y-coordinate of third point
z3	z-coordinate of third point

Details

Everything supplied to arguments must be numeric values or vectors of numeric values. The second point (x2, y2, z2) is treated as the vertex, and the angle between the three points in 3D space is computed.

Value

A numeric vector that provides the angular measurement in degrees.
