## S3 method for class 'DMFA'
plot(x, axes = c(1, 2), choix = "ind", label="all",
    lim.cos2.var = 0., xlim=NULL, ylim=NULL, title = NULL,
    palette = NULL, new.plot = FALSE, 
	autoLab = c("auto","yes","no"), ...)

Arguments

x

an object of class DMFA

axes

a length 2 vector specifying the components to plot

choix

the graph to plot ("ind" for the individuals, "var" for the variables)

label

a list of character for the elements which are labelled (by default, all the elements are labelled ("ind", ind.sup", "quali", "var", "quanti.sup"))

lim.cos2.var

value of the square cosinus under the variables are not drawn

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'

title

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

palette

the color palette used to draw the points. By default colors are chosen. If you want to define the colors : palette=palette(c("black","red","blue")); or you can use: palette=palette(rainbow(30)), or in black and white for example: palette=palette(gray(seq(0,.9,len=25)))

new.plot

boolean, if TRUE, a new graphical device is created

autoLab

if autoLab="auto", autoLab is equal to "yes" if there are less than 50 elements and "no" otherwise; if "yes", the labels of the drawn elements are placed in a "good" way (can be time-consuming if many elements), and if "no" the elements are placed quickly but may overlap

...

further arguments passed to or from other methods

Value

Returns the individuals factor map and the variables factor map, the partial variables representation and the groups factor map.
