Graphs to study one factor in a Multiple Correspondence Analysis

performs the canonical graph of a Multiple Correspondence Analysis.

Usage

# S3 method for acm
score(x, xax = 1, which.var = NULL, mfrow = NULL, 
    sub = names(oritab), csub = 2, possub = "topleft", ...)

Arguments

x: an object of class acm
xax: the column number for the used axis
which.var: the numbers of the kept columns for the analysis, otherwise all columns
mfrow: a vector of the form "c(nr,nc)", otherwise computed by a special own function n2mfrow
sub: a vector of strings of characters to be inserted as sub-titles, otherwise the variable names of the initial array
csub: a character size for the sub-titles
possub: a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")
...: further arguments passed to or from other methods
