In nfrerebeau/FactoHelpeR: Extract and Visualize FactoMineR Results

Description

Extract multivariate exploratory data analysis results.

Usage

extract(x, ...)

## S3 method for class 'PCA'
extract(x, select, ...)

## S3 method for class 'CA'
extract(x, select, ...)

Arguments

x	An object of class PCA or CA.
...	Currently not used.
select	A character string specifying the data to extract (see details).

Details

select must be a character string consisting of one or two terms separated by a single space.

If select is missing, a vector containing all possible choices is returned.

Value

A data frame.

Examples

library(FactoMineR)

# PCA
data(decathlon)
res_pca <- FactoMineR::PCA(decathlon, scale.unit = TRUE, quanti.sup = 11:12,
                           quali.sup = 13, graph = FALSE)
## Get eigenvalues
extract(res_pca, "eig")
## Get individuals coordinates
extract(res_pca, "ind coord")
## Get individuals cos2
extract(res_pca, "ind cos2")
## Get variables contribution
extract(res_pca, "var contrib")

# CA
data(children)
res_ca <- FactoMineR::CA(children, row.sup = 15:18, col.sup = 6:8,
                         graph = FALSE)
## Get eigenvalues
extract(res_ca, "eig")
## Get individuals coordinates
extract(res_ca, "row coord")
## Get variables contribution
extract(res_ca, "col contrib")
## Get singular values
extract(res_ca, "svd vs")
