# get_famd: Extract the results for individuals and variables - FAMD In factoextra: Extract and Visualize the Results of Multivariate Data Analyses

## Description

Extract all the results (coordinates, squared cosine and contributions) for the active individuals and variables from Factor Analysis of Mixed Date (FAMD) outputs.

• get_famd(): Extract the results for variables and individuals

• get_famd_ind(): Extract the results for individuals only

• get_famd_var(): Extract the results for quantitative and qualitative variables only

## Usage

 ```1 2 3 4 5``` ```get_famd(res.famd, element = c("ind", "var", "quanti.var", "quali.var")) get_famd_ind(res.famd) get_famd_var(res.famd, element = c("var", "quanti.var", "quali.var")) ```

## Arguments

 `res.famd` an object of class FAMD [FactoMineR]. `element` the element to subset from the output. Possible values are "ind", "quanti.var" or "quali.var".

## Value

a list of matrices containing the results for the active individuals and variables, including :

 `coord` coordinates of indiiduals/variables. `cos2` cos2 values representing the quality of representation on the factor map. `contrib` contributions of individuals / variables to the principal components.
