Free choice profiling with confidence ellipses

1 2 3 |

`X` |
data.frame |

`group` |
a list indicating the number of variables in each group; used when method="freechoice" or method="hsort" |

`scale` |
boolean, used when method="freechoice"; if TRUE, the variables are scaled |

`ncp` |
number of components used to procrustes the virtual subspaces on the true subspace; NULL by default and the number of components is estimated |

`axes` |
a length 2 vector specifying the components to plot |

`name.group` |
the names of each group of variables |

`level.conf` |
confidence level used to construct the ellipses. By default, 0.95 |

`nbsim` |
the number of simulations (corresponding to the number of virtual panels) used to compute the ellipses |

`nbchoix` |
the number of panelists forming a virtual panel, by default the number of panelists in the original panel |

`cex` |
cf. function |

`color` |
a vector with the colors used; by default there are 35 colors defined |

`title` |
string corresponding to the title of the graph you draw (by default NULL and a title is chosen) |

`new.plot` |
boolean, if TRUE, a new graphical device is created |

`graph` |
list with the graphs to draw; "ind", "var" and "ellipse" by default |

Perform MFA on the data frame and calculate confidence ellipses around the products

Returns a list with the result of the MFA and the bootstraped results that can be used with the plotellipse function.
