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 ggplot2-based 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 |
