sig.tot.inertia.perm

Permuted significance of the CA total inertia

Description

This function calculates the permuted significance of CA total inertia. Number of permutation is customizable (set at 999 by default). A frequency distribution histogram of permuted CA total inertia is produces and p.value of the observed total inertia is reported.

Usage

sig.tot.inertia.perm(data, B = 999)

Arguments

`data`	Name of the dataset (must be in dataframe format).
`B`	Number of permutations (999 by default).

Examples

data(greenacre_data)

#Returns the frequency distribution histogram of the permuted total inertia
#(using 99 permutations). The observed total inertia and the 95th percentile
#of the permuted inertia are also displayed for testing the significance
#of the observed total inertia.

sig.tot.inertia.perm(greenacre_data, 99)
