Get Contributions

Description

Get Contributions

Usage

get_contributions(x, ...)

get_correlations(x, ...)

get_cos2(x, ...)

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

## S4 method for signature 'PCA'
get_correlations(x, sup_name = ".sup")

## S4 method for signature 'MultivariateAnalysis'
get_cos2(x, margin = 1, sup_name = ".sup")

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.
sup_name	A character string specifying the name of the column to create for supplementary points attribution (see below).

Value

• get_contributions() returns a data.frame of contributions to the definition of the principal dimensions.

• get_correlations() returns a data.frame of correlations between variables and dimensions. An extra column (named after sup_name) is added specifying whether an observation is a supplementary point or not.

• get_cos2() returns a data.frame of cos^2 values (i.e. quality of the representation of the points on the factor map). An extra column (named after sup_name) is added specifying whether an observation is a supplementary point or not.
