`data` |
dataframe. In wide format. Only numeric columns will be used. |

`group` |
vector. Vector indicating group membership for each observation in |

`B` |
integer. Number of bootstrap samples per subgroup. |

`comp` |
integer vector. Specifies the principal components whose proportion of variation must be returned. Defaults to 1:2. |

`locType` |
character. Specifies measure of location to use. Options are mean, cmwed (column-wise median), oja, weisz (geometric median) and gmed (a fast version for the geometric median). |

`pointSize` |
numeric. Size of plot points |

`quant` |
logical. If |

`boot` |
logical. If TRUE, then bootstrap is re-performed. If FALSE, then
bootstrap values are taken from object with name |

`save` |
logical. If |

`name` |
character. Name of object in |

`env` |
environment. Environment to save bootstrapped values to. |

`path` |
character. Path of to save bootstrapped values to, or load bootstrapped values from. |

`textAdjVal` |
numeric. Value that controls the degree to which the axis labels are shifted from the endpoints of the axes. Higher values move the axis further right and up. |

`axesLenRatio` |
numeric. If not NULL, then the ratio of the length of the y-axis divided by the
x-axis is made equal to |

`qualCutoff` |
numberic. The minimum sum of the axis predictivity across the principal components selected (by |

`selAxisLab` |
character vector. Names of columns in |

`arrow` |
logical. If TRUE, then arrows instead of lines are plotted for the axes. The arrows point from the origin to the largest observed value for its variable on the biplot axis. |

`arrowSize` |
numeric. Size of the arrows for |

`fontScaleFactor` |
numeric. Ratio by which to multiply the default font size. |
