R: Extract the results for individuals and variables - FAMD

get_famd {factoextra} | R Documentation

## Extract the results for individuals and variables - FAMD

### 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

    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.

### Examples

     # Compute FAMD
     library("FactoMineR")
     data(wine)
     res.famd <- FAMD(wine[,c(1,2, 16, 22, 29, 28, 30,31)], graph = FALSE)

     # Extract the results for qualitative variable categories
     quali.var <- get_famd_var(res.famd, "quali.var")
     print(quali.var)
     head(quali.var$coord) # coordinates of qualitative variables

     # Extract the results for quantitative variables
     quanti.var <- get_famd_var(res.famd, "quanti.var")
     print(quanti.var)
     head(quanti.var$coord) # coordinates

     # Extract the results for individuals
     ind <- get_famd_ind(res.famd)
     print(ind)
     head(ind$coord) # coordinates of individuals
