cone3d

Draws a cone in 3D from a <code>base</code> point to a <code>tip</code> point, with a given <code>radius</code> at the base.
This is used to draw nice arrow heads in <code>arrows3d</code>.

A collection of matrix functions for teaching and learning matrix
linear algebra as used in multivariate statistical methods. These functions are
mainly for tutorial purposes in learning matrix algebra ideas using R. In some
cases, functions are provided for concepts available elsewhere in R, but where
the function call or name is not obvious. In other cases, functions are provided
to show or demonstrate an algorithm. In addition, a collection of functions are
provided for drawing vector diagrams in 2D and 3D.
