simplex: Hausdorff distances between the convex hulls of two point...

In disp2D: 2D Hausdorff and Simplex Dispersion Orderings

Description

From an original 2D point set, different two bootstrap samples are obtained and the Hausdorff distances between them evaluated.

Usage

simplex(x, bootstrap = TRUE, nresamples = 10)

Arguments

x	A matrix.
bootstrap	bootstrap = TRUE then we take two bootstrap samples.
nresamples	A positive integer indicating the number of two bootstrap samples.

Value

Hausdorff distances between the convex hulls.
