Description

Get Eigenvalues

Usage

get_eigenvalues(x)

get_variance(x, ...)

get_inertia(x, ...)

## S4 method for signature 'MultivariateAnalysis'
get_distances(x, margin = 1)

## S4 method for signature 'MultivariateAnalysis'
get_eigenvalues(x)

## S4 method for signature 'PCOA'
get_eigenvalues(x)

## S4 method for signature 'MultivariateAnalysis'
get_inertia(x, margin = 1)

## S4 method for signature 'MultivariateAnalysis'

Arguments

x	An object from which to get element(s) (a CA, MCA or PCA object).
...	Currently not used.
margin	A length-one numeric vector giving the subscript which the data will be returned: 1 indicates individuals/rows (the default), 2 indicates variables/columns.
digits	An integer indicating the number of decimal places to be used.

Value

• get_eigenvalues() returns a data.frame with the following columns: eigenvalues, variance (percentage of variance) and cumulative (cumulative percentage of variance).

• get_variance() returns a numeric vector giving the amount of variance explained by each (principal) component.

• get_distance()returns a numeric vector of squared distance to the centroid.

• get_inertia() returns a numeric vector giving the inertia (weighted squared distance to the centroid).
