`x` |
fraction of first component
OR 3-element vector (for all three components, omitting |

`y` |
(optional) fraction of second component. |

`z` |
(optional) fraction of third component. |

`lcol` |
line color |

`pch` |
plotting character. |

`...` |
Further graphical parameters (see |

Adds a (single!) point and lines to an existing plot (generated by `triplot`

).
The lines originate from the point and run (perpendicular) towards all three sides.
The lengths (and proportions) of these lines are identical to those of `x`

, `y`

and `z`

.

a 2-column-matrix containing plot coordinates.
