In gensphere: Generalized Spherical Distributions

Description

Miscellaneous internal functions for the gensphere package.

Usage

gs.cone(x, mu, theta0)
gs.elliptical(x, B)
gs.gen.lp.norm(x, p, A)
gs.lp.norm(x,p)
gs.proj.normal(x, mu, sigma)
gs.vfunc.eval(cfunc, x)
gs.pdf2d.plot(gs.dist, xy.grid = seq(-10, 10, 0.1) )
RefineSphericalTessellation(V1, V2)
NearbyPointsOnSphere(x, epsilon)
RotateInNDimensions(x, y)
## S3 method for class 'gensphere.contour'
print(x,...)
## S3 method for class 'gensphere.distribution'
print(x,...)
## S3 method for class 'gensphere.contour'
plot(x,multiplier=1,...)

Arguments

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 gensphere
xy.grid	a matrix of (x,y) values in 2-dimensions
cfunc	an object of class "gensphere.contour" defined by cfunc.new, etc.
...	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

Details

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.
