`x,y` |
vectors representing points in d-dimensional space |

`mu` |
direction of the mode for a cone/normal bump |

`theta0` |
angle between peak of the cone and the base of the cone |

`B` |
(d x d) positive definite shape matrix |

`A` |
matrix used to compute || A x ||_p |

`p` |
power of the l^p norm; p=2 is Euclidean distance |

`gs.dist` |
object of class "gensphere.distribution" defined by |

`xy.grid` |
a matrix of (x,y) values in 2-dimensions |

`cfunc` |
an object of class "gensphere.contour" defined by |

`...` |
optional arguments to the 2-dimensional plot, e.g. col='red', etc. |

`sigma` |
scale parameter for a normal bump |

`epsilon` |
vector of positive numbers where there are points added around a particular direction |

`V1,V2` |
matrices of vertices which are joined together to get a refinement of the grid |

`multiplier` |
a positive number used to scale the contour |

These are undocumented functions that are used internally. The functions
`gs.cone`

, `gs.elliptical`

, `gs.gen.lp.norm`

, `gs.lp.norm`

,
`gs.proj.normal`

, `gs.vfunc.eval`

are used in evalutating a contour function.
`RefineSphericalTessellation`

, `NearbyPointsOnSphere`

are used in defining
the tessellation of the contour that identifies bumps and cones.
`gs.pdf2d.plot`

and the plot/print methods are initial attempts at plotting and
printing a summary of objects.

These functions may change or disappear in the future.
