gf_ellipse | R Documentation |

Formula interface to `ggplot2::stat_ellipse()`

.

gf_ellipse( object = NULL, gformula = NULL, data = NULL, ..., alpha, color, group, type = "t", level = 0.95, segments = 51, xlab, ylab, title, subtitle, caption, geom = "path", stat = "ellipse", position = "identity", show.legend = NA, show.help = NULL, inherit = TRUE, environment = parent.frame() )

`object` |
When chaining, this holds an object produced in the earlier portions of the chain. Most users can safely ignore this argument. See details and examples. |

`gformula` |
A formula with shape |

`data` |
A data frame with the variables to be plotted. |

`...` |
Additional arguments. Typically these are
(a) ggplot2 aesthetics to be set with |

`alpha` |
Opacity (0 = invisible, 1 = opaque). |

`color` |
A color or a formula used for mapping color. |

`group` |
Used for grouping. |

`type` |
The type of ellipse.
The default |

`level` |
The level at which to draw an ellipse,
or, if |

`segments` |
The number of segments to be used in drawing the ellipse. |

`xlab` |
Label for x-axis. See also |

`ylab` |
Label for y-axis. See also |

`title, subtitle, caption` |
Title, sub-title, and caption for the plot.
See also |

`geom` |
Geom for drawing ellipse. Note: |

`stat` |
A character string naming the stat used to make the layer. |

`position` |
Either a character string naming the position function used for the layer or a position object returned from a call to a position function. |

`show.legend` |
A logical indicating whether this layer should be included in
the legends. |

`show.help` |
If |

`inherit` |
A logical indicating whether default attributes are inherited. |

`environment` |
An environment in which to look for variables not found in |
