vector of \(x,y,z\) coordinates to be plotted. If
 <code>x</code> is a matrix, interpret the rows as 3D Cartesian coordinates

x,y,z

Limits of plot in the \(x,y,z\) directions,
 with default <code>NULL</code> meaning to use <code>range()</code>

xlim,ylim,zlim

E-folding distance for graying out (depths are standardized
 to be between 0 and 1)

The hue for the points, with default value of 1 corresponding
 to red. If <code>NULL</code>, produce black points greying to white

Further arguments passed to <code>persp()</code> and
 <code>points()</code>

&#8230;

Three dimensional plotting of points. Produces a nice-looking 3D
 scatterplot with greying out of further points givin a visual depth cue

Quaternions and Octonions are four- and eight- dimensional
extensions of the complex numbers.  They are normed division
algebras over the real numbers and find applications in spatial
rotations (quaternions), and string theory and relativity
(octonions).  The quaternions are noncommutative and the octonions
nonassociative.  See the package vignette for more details.
