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 Data (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", "quali.sup")
)

get_famd_ind(res.famd)

get_famd_var(
  res.famd,
  element = c("var", "quanti.var", "quali.var", "quali.sup")
)

Arguments

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

Value

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

coord	coordinates of individuals/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)
 res.famd.sup <- FAMD(wine[,c(1,2, 16, 22, 29, 28, 30,31)],
                      sup.var = 2, 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 supplementary qualitative variable categories
 quali.sup <- get_famd_var(res.famd.sup, "quali.sup")
 print(quali.sup)
 head(quali.sup$coord) # coordinates of supplementary 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
