This function is designed to display the interaction between two qualitative variables, in most cases
the *product* and the *session* variables.

1 2 | ```
graphinter(donnee, col.p, col.j, firstvar, lastvar=ncol(donnee),
numr = 2,numc = 2)
``` |

`donnee` |
a data frame made up of at least two qualitative variables
( |

`col.p` |
the position of one categorical variables of interest (the |

`col.j` |
the position of one categorical variables of interest (the |

`firstvar` |
the position of the first endogenous variable |

`lastvar` |
the position of the last endogenous variable (by default the last column of |

`numr` |
the number of graphs per row (by default 2) |

`numc` |
the number of graphs per column (by default 2) |

The data set must be balanced (or not unbalanced too much).

If the variables of interest are the *product* and the *session* variables,
a list containing the following components:

`prod` |
a data frame of dimension ( |

`seance` |
as many matrices of dimension ( |

The graphical display of the interaction for each sensory descriptor.
