Description Usage Arguments Value

View source: R/min_cut.R

Description

Finds the normalised cut across the best hyperplane orthogonal to a given projection vector. Used as projection index for projection pursuit to find minimum normalised cut hyperplanes.

Usage

1
f_ncut(v, X, P)

Arguments

v

a numeric vector of length ncol(X)

X

a numeric matrix (num_data x num_dimensions) to be projected on v

P

a list of parameters including (at least) $s (positive numeric scaling parameter), $nmin (positive integer minimum cluster size)

Value

the value of the normalised cut across the best hyperplane orthogonal to v
