fviz_hmfa {factoextra}  R Documentation 
Hierarchical Multiple Factor Analysis (HMFA) is, an extension of
MFA, used in a situation where the data are organized into a hierarchical
structure. fviz_hmfa() provides ggplot2based elegant visualization of HMFA
outputs from the R function: HMFA [FactoMineR].
fviz_hmfa_ind(): Graph of individuals
fviz_hmfa_var(): Graph of variables
fviz_hmfa_quali_biplot(): Biplot of individuals and qualitative variables
fviz_hmfa(): An alias of fviz_hmfa_ind()

fviz_hmfa(X, ...)
X 
an object of class HMFA [FactoMineR]. 
axes 
a numeric vector of length 2 specifying the dimensions to be plotted. 
geom 
a text specifying the geometry to be used for the graph. Allowed
values are the combination of 
repel 
a boolean, whether to use ggrepel to avoid overplotting text labels or not. 
habillage 
an optional factor variable for coloring the observations by groups. Default value is "none". If X is an HMFA object from FactoMineR package, habillage can also specify the index of the factor variable in the data. 
addEllipses 
logical value. If TRUE, draws ellipses around the individuals when habillage != "none". 
shape.ind , shape.var 
point shapes of individuals and variables, respectively. 
col.ind , col.var 
color for individuals, partial individuals and variables, respectively. Can be a continuous variable or a factor variable. Possible values include also : "cos2", "contrib", "coord", "x" or "y". In this case, the colors for individuals/variables are automatically controlled by their qualities ("cos2"), contributions ("contrib"), coordinates (x^2 + y^2 , "coord"), x values("x") or y values("y"). To use automatic coloring (by cos2, contrib, ....), make sure that habillage ="none". 
col.ind.sup 
color for supplementary individuals 
alpha.ind , alpha.var 
controls the transparency of individual, partial individual and variable, respectively. The value can variate from 0 (total transparency) to 1 (no transparency). Default value is 1. Possible values include also : "cos2", "contrib", "coord", "x" or "y". In this case, the transparency for individual/variable colors are automatically controlled by their qualities ("cos2"), contributions ("contrib"), coordinates (x^2 + y^2 , "coord"), x values("x") or y values("y"). To use this, make sure that habillage ="none". 
select.ind , select.var 
a selection of individuals and variables to be drawn. Allowed values are NULL or a list containing the arguments name, cos2 or contrib:

partial 
list of the individuals for which the partial points should be drawn. (by default, partial = NULL and no partial points are drawn). Use partial = "All" to visualize partial points for all individuals. 
col.partial 
color for partial individuals. By default, points are colored according to the groups. 
group.names 
a vector containing the name of the groups (by default, NULL and the group are named group.1, group.2 and so on). 
node.level 
a single number indicating the HMFA node level to plot. 
... 
Arguments to be passed to the function fviz() and ggpubr::ggpar() 
choice 
the graph to plot. Allowed values include one of c("quanti.var", "quali.var", "group") for plotting quantitative variables, qualitative variables and group of variables, respectively. 
col.var.sup 
color for supplementary variables. 
title 
the title of the graph 
a ggplot
