For objects of class FactoClass it graphs a factorial plane showing the center of gravity of the cluster, and identifying with colors the cluster to which each element belongs.

`FC ` |
object of class FactoClass. |

`x` |
number indentifying the factor to be used as horizontal axis. Default x=1 |

`y` |
number indentifying the factor to be used as vertical axis. Default y=2 |

`xlim` |
the x limits (x1, x2) of the plot |

`ylim` |
the y limits of the plot |

`rotx ` |
TRUE if you want change the sign of the horizontal coordinates (default FALSE). |

`roty ` |
TRUE if you want change the sign of the vertical coordinates (default FALSE). |

`roweti ` |
selected row points for the graphic. Default all points. |

`coleti ` |
selected column points for the graphic. Default all points. |

`titre ` |
graphics title. |

`axislabel ` |
if it is TRUE the axis information is written. |

`col.row ` |
color for row points and row labels. Default |

`col.col ` |
color for column points and column labels. Default "grey55". |

`cex ` |
global scale for the labels. Default cex=0.8. |

`cex.row ` |
scale for row points and row labels. Default cex.row=0.8. |

`cex.col ` |
scale for column points and column labels. Default cex.col=0.8. |

`cex.clu ` |
scale for cluster points and cluster labels. (default cex.row). |

`all.point ` |
if if is TRUE, all points are outlined. Default all.point=TRUE. |

`Trow ` |
if it is TRUE the row points are outlined. Default TRUE. |

`Tcol ` |
if it is TRUE the column points are outlined. Default TRUE. |

`nclus ` |
labels for the clusters (default cl1, cl2, ... |

`cframe ` |
scale for graphics limits |

`ucal ` |
quality Representation Threshold in the plane. Default ucal=0 |

`cex.global` |
scale for the label sizes |

`infaxes` |
place to put the axes information: "out","in","no". Default infaxes="out".
If infaxes="out" the graphic is similar to |

`cstar` |
length of the rays between the centroids of the classes and their points |

It draws the factorial plane with the clusters. Only for objects `FactoClass`

see FactoClass. The factorial plane is drawn with `planfac`

and the classes
are projected with `s.class`

of `ade4`

It draws the factorial plane x, y using $co, $li of the object of class `FactoClass`

.
If ucal > 0, the function inertia.dudi is used to calculate the quality of representation
in the plane.
