In Directional: A Collection of Functions for Directional Data Analysis

Euclidean transformation

Description

It transforms the data from the spherical coordinates to Euclidean coordinates.

Usage

euclid(u)

Arguments

u	A two column matrix or even one single vector, where the first column (or element) is the latitude and the second is the longitude. The order is important.

Details

It takes the matrix of unit vectors of latitude and longitude and transforms it to unit vectors.

Value

A three column matrix:

U	The Euclidean coordinates of the latitude and longitude.
