`X` |
n*d data matrix of real numbers |

`Y` |
n*1 data matrix of real numbers; response variable |

`xmargin` |
positive real number; empty space in left and right |

`paletti` |
n vector of colors; the lines will be colored with these colors |

`noadd` |
TRUE or FALSE; if FALSE, then the lines will be added to an existing plot |

`col.verti.y` |
a caharacter; the name of a color |

`digits` |
a natural number; the number of digits in the annotation |

`arg` |
d*1 vector; the current value of the explanatory variable |

`colarg` |
a character; the name of a color |

`lwd` |
a positive real number; the width of the lines |
