Sample n points uniformly on a disc of radius r in
two-dimensional euclidean space via transformation to polar coordinates:
the angle is sampled uniformly from \(U(0,2\pi)\), the length is
sampled uniformly from \(\sqrt{U(0,r^2)}\). The sampled polar
coordinates are then back-transformed to cartesian coordinates.
Usage
runifdisc(n, r = 1, buffer = 0)
Value
A two-column coordinate matrix of the sampled points.
