Plot the graphs for a Principal Component Analysis (DMFA) with supplementary individuals, supplementary quantitative variables and supplementary categorical variables.
# S3 method for 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"), ...)Returns the individuals factor map and the variables factor map, the partial variables representation and the groups factor map.
an object of class DMFA
a length 2 vector specifying the components to plot
the graph to plot ("ind" for the individuals, "var" for the variables)
a list of character for the elements which are labelled (by default, all the elements are labelled ("ind", ind.sup", "quali", "var", "quanti.sup"))
value of the square cosinus under the variables are not drawn
range for the plotted 'x' values, defaulting to the range of the finite values of 'x'
range for the plotted 'y' values, defaulting to the range of the finite values of 'y'
string corresponding to the title of the graph you draw (by default NULL and a title is chosen)
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)))
boolean, if TRUE, a new graphical device is created
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
