Description Usage Arguments Details Author(s) Examples

A simple alternative to the traditional Venn diagram. It depicts each overlap as a separate bubble with area proportional to the overlap size.

1 2 |

`sets` |
list of vectors to overlap. If list contains more than 3 elements only the first 3 are used. |

`percentage` |
logical showing if percentages or raw numbers are displayed |

`colors` |
vector of colors for the bubbles, see details on specifying that |

`fontsize` |
fontsize used for the numbers in the bubbles |

`main` |
title of the plot |

`scale` |
a scaling factor to adjust the base triangle size when the plot does not fit the window well. |

`add` |
logical determining if the figure is added to exixting plot or if a new plot is initialized |

Colors can be specified as vector. For 2 set case a 3 element vector is required with colors for: Set1, Set2 and Set1 & Set2 correspondingly. For 3 set case a 7 element vector is required with colors for: Set1, Set2, Set3, Set1 & Set2, Set1 & Set3, Set2 & Set3 and Set1 & Set2 & Set3 correspondingly.
