print.CA3variants | R Documentation |

This function prints the results of three-way symmetrical or non-symmetrical correspondence analysis.
If the input parameter, in CA3variants, is `ca3type="CA3"`

, the function prints the results
of three-way symmetrical correspondence analysis.
If the input parameter, in `CA3variants`

, is `ca3type="NSCA3"`

,
the function prints the results of three-way non-symmetrical correspondence analysis.
If the input parameter, in `CA3variants`

, is `ca3type="OCA3"`

,
the function prints the results of ordered three-way symmetrical correspondence analysis.
If the input parameter, in `CA3variants`

, is `ca3type="ONSCA3"`

,
the function prints the results of ordered three-way non-symmetrical correspondence analysis.
When the input parameter, in `print.CA3variants`

, is `digits = 3`

,
the function prints all the results using three digital numbers.

## S3 method for class 'CA3variants' print(x, printall= FALSE, digits = 3,...)

`x` |
The name of the output of the main function |

`printall` |
The logical parameter that specifies if to print all the results or some of them. By default, |

`digits` |
The input parameter specifying the digital number. By default, |

`...` |
Further arguments passed to or from other methods. |

The value of output returned depends on the kind of three-way correspondence analysis variant performed. It also gives the number of the iteration of the algorithm to reach the convergence of the solution. Depending on the variant of three-way correspondence analysis performed, it gives the related weighted contingency table, the reconstructed table by the components and core array, the explained inertia, the total inertia, the inertia in percentage, the proportion of explained inertia given the defined number of the components, the row standard and principal coordinates, the interactive column-tube standard and principal coordinates, the inner-product matrix of coordinates, the core array and index partitioning.
