Generating a sample of points on a pipe — pipe

Points are drawn from a uniform distribution between -1 and 1, the pipe structure is generated by rejecting points if they are not on a circle with radius 1 and thickness t in the last two parameters.

Usage

pipe_data(n, p, t = 0.1)

Arguments

n: number of sample points to generate
p: sample dimensionality
t: thickness of circle, default=0.1

Value

sample points in tibble format

Examples
