Performs Multiple Factor Analysis, drawing on the work of Escoffier and Pages (1994). It allows the use of MCA variants (e.g. specific MCA or class specific MCA) as inputs.

1 |

`l_mca` |
a list of objects of class |

`ncp` |
number of dimensions kept in the results (default is 5) |

`compute.rv` |
whether RV coefficients should be computed or not (default is FALSE, which makes the function execute faster) |

This function binds individual coordinates from every MCA in `l_mca`

argument, weights them by the first eigenvalue,
and the resulting data frame is used as input for Principal Component Analysis (PCA).

Returns an object of class `'multiMCA'`

, i.e. a list:

`eig` |
a list of numeric vector for eigenvalues, percentage of variance and cumulative percentage of variance |

`var` |
a list of matrices with results for input MCAs components (coordinates, correlation between variables and axes, square cosine, contributions) |

`ind` |
a list of matrices with results for individuals (coordinates, square cosine, contributions) |

`call` |
a list with informations about input data |

`VAR` |
a list of matrices with results for categories and variables in the input MCAs (coordinates, square cosine, test-values, variances) |

`my.mca` |
lists the content of the objects in |

`RV` |
a matrix of RV coefficients |

## Performs a specific MCA on music variables of 'Taste' example data set,

## and then a Multiple Factor Analysis.
