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)
