angle3d {aRchi}R Documentation

Calculate the zenith angle from xyz coordinates

Description

Calculate a zenith angle between two segments from 3d (i.e x,y,z) coordinates

Usage

angle3d(o, a, b)

Arguments

o

3d coordinates of the common point of the two segments

a

3d coordinates of the other point of segment a

b

3d coordinates of the other point of segment b

Value

The angle in degree

Examples

origin=c(0,0,0)
a=c(0,0,1)
b=c(1,0,0)

angle3d(o=origin,a=a,b=b)
