Utility Functions for nFactors Class Objects

Description

Utility functions for nFactors class objects.

Usage

is.nFactors(x)

## S3 method for class 'nFactors'
print(x, ...)

## S3 method for class 'nFactors'
summary(object, ...)

Arguments

x	nFactors: an object of the class nFactors
...	variable: additionnal parameters to give to the print function with print.nFactors or to the summary function with summary.nFactors
object	nFactors: an object of the class nFactors

Value

Generic functions for the nFactors class:

is.nFactors	logical: is the object of the class nFactors?
print.nFactors	numeric: vector of the number of components/factors to retain: same as the nFactors vector from the nFactors object
summary.nFactors	data.frame: details of the results from a nFactors object: same as the details data.frame from the nFactors object, but with easier control of the number of decimals with the digits parameter

Examples

## SIMPLE EXAMPLE
 data(dFactors)
 eig      <- dFactors$Raiche$eigenvalues
 N        <- dFactors$Raiche$nsubjects

 res <- nBartlett(eig,N); res; is.nFactors(res); summary(res, digits=2)
 res <- nBentler(eig,N);  res; is.nFactors(res); summary(res, digits=2)
 res <- nCng(eig);        res; is.nFactors(res); summary(res, digits=2)
 res <- nMreg(eig);       res; is.nFactors(res); summary(res, digits=2)
 res <- nSeScree(eig);    res; is.nFactors(res); summary(res, digits=2)

## SIMILAR RESULTS, BUT NOT A nFactors OBJECT
 res <- nScree(eig);      res; is.nFactors(res); summary(res, digits=2)
