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

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
