hcRandomPairs: Random hierarchical structure

Description

Create a hierarchical structure using a random hierarchical partition of the data.

Usage

hcRandomPairs(data, seed = NULL, ...)

Value

A numeric two-column matrix in which the ith row gives the minimum index for observations in each of the two clusters merged at the

Arguments

data

A numeric matrix or data frame of observations. If a matrix or data frame, rows correspond to observations and columns correspond to variables.
