plot.CA {FactoMineR}R Documentation

Draw the Correspondance Analysis (CA) graphs

Description

Draw the Correspondance Analysis (CA) graphs.

Usage

plot.CA(x, axes = c(1, 2),
    xlim = NULL, ylim = NULL, invisible = NULL, col.row = "blue",
    col.col = "red", col.row.sup = "darkblue", 
    col.col.sup = "darkred", label = "all", cex = 1, 
    title = NULL, palette = NULL, ...)

Arguments

x an object of class CA
axes a length 2 vector specifying the components to plot
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'
invisible string indicating if some points should be unlabelled ("row", "col", "row.sup", "col.sup")
col.row a color for the rows points
col.col a color for columns points
col.row.sup a color for the supplementary rows points
col.col.sup a color for supplementary columns points
label a list of character for the elements which are labelled (by default, all the elements are labelled ("row", "row.sup", "col", "col.sup"
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)
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)))
... further arguments passed to or from other methods

Value

Returns the individuals factor map and the variables factor map.
