triangle.class | R Documentation |

Function to plot triangular data (i.e. dataframe with 3 columns of
positive or null values) and a partition

triangle.class(ta, fac, col = rep(1, length(levels(fac))), wt = rep(1, length(fac)), cstar = 1, cellipse = 0, axesell = TRUE, label = levels(fac), clabel = 1, cpoint = 1, pch = 20, draw.line = TRUE, addaxes = FALSE, addmean = FALSE, labeltriangle = TRUE, sub = "", csub = 1, possub = "bottomright", show.position = TRUE, scale = TRUE, min3 = NULL, max3 = NULL)

`ta` |
a data frame with 3 columns of null or positive numbers |

`fac` |
a factor of length the row number of |

`col` |
a vector of color for showing the groups |

`wt` |
a vector of row weighting for the computation of the gravity centers by class |

`cstar` |
a character size for plotting the stars between 0 (no stars) and 1 (complete star) for a line linking a point to the gravity center of its belonging class. |

`cellipse` |
a positive coefficient for the inertia ellipse size |

`axesell` |
a logical value indicating whether the ellipse axes should be drawn |

`label` |
a vector of strings of characters for the labels of gravity centers |

`clabel` |
if not NULL, a character size for the labels, used with |

`cpoint` |
a character size for plotting the points, used with |

`pch` |
if |

`draw.line` |
a logical value indicating whether the triangular lines should be drawn |

`addaxes` |
a logical value indicating whether the axes should be plotted |

`addmean` |
a logical value indicating whether the mean point should be plotted |

`labeltriangle` |
a logical value indicating whether the varliable labels of |

`sub` |
a string of characters for the graph title |

`csub` |
a character size for plotting the graph title |

`possub` |
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright") |

`show.position` |
a logical value indicating whether the sub-triangle containing the data should be put back in the total triangle |

`scale` |
a logical value for the graph representation : the total triangle (FALSE) or the sub-triangle (TRUE) |

`min3` |
if not NULL, a vector with 3 numbers between 0 and 1 |

`max3` |
if not NULL, a vector with 3 numbers between 0 and 1. Let notice that |
