sample_uniform: Sample Uniformily from various objects centered at the origin

In jsilve24/driver: Utility Functions from Justin Silverman

Description

Sample Uniformily from various objects centered at the origin

Usage

rUnifSphere(n, D, radius = 1, shell_only = FALSE)

rUnifSimplex(n, D)

Arguments

n	number of samples to produce
D	dimension of object
radius	radius of sphere to sample from
shell_only	if TRUE samples from shell of object only, if false samples from entire region of object

Value

matrix of dimension D x n

Examples

# Sample Uniformily from Sphere (Full)
x <- rUnifSphere(1000, 2, 2)
plot(t(x), asp=1)

# Sample Uniformily from Sphere (Shell Only)
x <- rUnifSphere(1000, 2, 2, shell_only=TRUE)
plot(t(x), asp=1)

# Sample Uniformily from Simplex
x <- rUnifSimplex(1000, 2)
plot(t(x), asp=1)
