nFactorsObjectMethods: Utility Functions for nScree Class Objects

Description

Utility functions for nFactors class objects.

Usage

## S3 method for class 'nFactors':
is     (object)
 ## S3 method for class 'nFactors':
print  (x, ...)
 ## S3 method for class 'nFactors':
summary(object, ...)

Arguments

x

nFactors: an object of the class nFactors

object

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

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 nFacors OBJECT
 res <- nScree(eig);      res; is.nFactors(res); summary(res, digits=2)
