mcoa: Multiple CO-inertia Analysis

Description

performs a multiple CO-inertia analysis, using an object of class ktab.

Usage

mcoa(X, option = c("inertia", "lambda1", "uniform", "internal"),  scannf = TRUE, nf = 3, tol = 1e-07)
"print"(x, ...)
"summary"(object, ...)
"plot"(x, xax = 1, yax = 2, eig.bottom = TRUE, ...)

Arguments

X

an object of class ktab

option

a string of characters for the weightings of the arrays options :

scannf

a logical value indicating whether the eigenvalues bar plot should be displayed

nf

if scannf FALSE, an integer indicating the number of kept axes

tol

a tolerance threshold, an eigenvalue is considered positive if it is larger than -tol*lambda1 where lambda1 is the largest eigenvalue.

x, object

an object of class 'mcoa'

...

further arguments passed to or from other methods

xax, yax

the numbers of the x-axis and the y-axis

eig.bottom

a logical value indicating whether the eigenvalues bar plot should be added

Value

mcoa returns a list of class 'mcoa' containing :
