Project a path onto the unit sphere

Description

This function takes a path in d dimensional space and projects it onto the d-1 sphere. It takes as additional arguments the starting and ending points under consideration and the dimension to be considered.

Usage

projectPathToSphere(path, from = 1, to = nrow(path), d = ncol(path))

Arguments

path	- This is an mxn dimensional matrix. Each row is considered a point.
from	- The starting place along the path which will be treated as the center of the sphere. This defaults to 1.
to	- The end point of the path. This defaults to nrow(path).
d	- The dimension under consideration. This defaults to ncol(path)

Value

This returns a projection of the path onto the d-1 sphere in the form of a (to - from) x d matrix.

Examples

projection1 = projectPathToSphere(straight_path)
projection2 = projectPathToSphere(crooked_path,from=6)
