Inertia: Measure of inertia

In ManonMartin/MBXUCL: R Routines for metabolomic data

Description

Calculates the within, between and total inertia of a data matrix

Usage

Inertia(x, y, print = FALSE)

Arguments

x	A numeric matrix.
y	A numeric vector of data clusters.
print	If TRUE, prints the inertia values

Value

A list with the following elements:

Between_within

A matrix with the following elements: Name.group = Group membership, InertiaT = Total inertia, InertiaB = Between inertia, InertiaW = Within inertia.

Per_group

A matrix with the following elements: Inertia_group = Inertia per group, Inertia_group100 = Inertia per group (percentage of ITOT pergroup), Inertia_moy_group = Mean Inertia per group.

Examples

data('HumanSerum')
Res = Inertia(x = HumanSerumSpectra, y = ClassHS, print = TRUE)
