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).
