partial.wwm: Coordinates and Aids to Interpretation of Superimposed Representation of Double Intra Correspondence Analysis

Description

Coordinates and Aids to Interpretation of Superimposed Representation of Double Intra Correspondence Analysis

Usage

partial.wwm(ACww,dil = TRUE)
## S3 method for class 'parwwm':
print(x, \dots)
"wwm.util.addfactor<-"(x,value)

Arguments

ACww

an object of class wwmodel

dil

when dil=TRUE the partial column coordinates are multiplied by J and the partial column coordinates are multiplied by L

x

object of type parwwm

...

further arguments passed to or from other methods
