plot.MFA: Draw the Multiple Factor Analysis (MFA) graphs

Description

Draw the Multiple Factor Analysis (MFA) graphs.

Usage

plot.MFA(x, axes = c(1, 2), choix = "ind", ellipse = NULL, ellipse.par = NULL,
    lab.grpe = TRUE, lab.var = TRUE, lab.ind.moy = TRUE, 
    lab.par = FALSE, habillage = "ind", col.hab = NULL, 
    invisible = NULL, partial = NULL, lim.cos2.var = 0.1, 
    chrono = FALSE, xlim = NULL, ylim = NULL, 
    cex = 1, title = NULL, ...)

Arguments

x

an object of class MFA

axes

a length 2 vector specifying the components to plot

choix

a string corresponding to the graph that you want to do ("ind" for the individual or qualitative variables graph, "var" for the quantitative variables graph, "axes" for the graph of the partial axes, "group" for the groups representation)

ellipse

boolean (NULL by default), if not null, draw ellipses around the individuals, and use the results of coord.ellipse

ellipse.par

boolean (NULL by default), if not null, draw ellipses around the partial individuals, and use the results of coord.ellipse

lab.grpe

boolean, if TRUE, the label of the groups are drwan

lab.var

boolean, if TRUE, the label of the variables are drwan

lab.ind.moy

boolean, if TRUE, the label of the mean points are drwan

lab.par

boolean, if TRUE, the label of the partial points are drwan

habillage

string corresponding to the color which are used. If "ind", one color is used for each individual; if "group" the individuals are colored according to the group; else if it is the name or the position of a qualitative variable, it colors according to

col.hab

the colors to use. By default, colors are chosen

invisible

list of string; for choix ="ind", the individuals can be omit (invisible = "ind"), or supplementary individuals (invisible="ind.sup") or the centerg of gravity of the qualitative variables (invisible= "quali"); if invisible = c("ind","ind.sup"), just

partial

list of the individuals or of the center of gravity for which the partial points should be drawn (by default, partial = NULL and no partial points are drawn)

lim.cos2.var

value of the square cosinus under with the points are not drawn

chrono

boolean, if TRUE, the partial points of a same point are linked (useful when groups correspond to different moment)

xlim

range for the plotted 'x' values, defaulting to the range of the finite values of 'x'

ylim

range for the plotted 'y' values, defaulting to the range of the finite values of 'y'

cex

cf. function par in the graphics package

title

string corresponding to the title of the graph you draw (by default NULL and a title is chosen)

...

further arguments passed to or from other methods

Value

• Returns the individuals factor map and the variables factor map.
