Plot of the factorial maps in a Multiple Correspondence Analysis

performs the scatter diagrams of a Multiple Correspondence Analysis.

Usage

# S3 method for class 'acm'
scatter(x, xax = 1, yax = 2, mfrow=NULL, csub = 2, possub = "topleft", ...)

Arguments

x: an object of class acm
xax: the column number for the x-axis
yax: the column number for the y-axis
mfrow: a vector of the form "c(nr,nc)", if NULL (the default) is computed by n2mfrow
csub: a character size for the legend, used with par("cex")*csub
possub: a string of characters indicating the legend position ("topleft", "topright", "bottomleft", "bottomright") in a array of figures
...: further arguments passed to or from other methods
