Description Usage Arguments Value Examples

Calculates p-values from a conditional hypergeometric distribution: the distribution of how many items are in the overlap of all samples when samples of arbitrary size are each taken without replacement from populations of arbitrary size.

1 | ```
pvalchyper(k, s, n, m, tail = "upper", verbose = T)
``` |

`k` |
an integer or vector of integers representing the overlap size |

`s` |
an integer representing the size of the intersecting population |

`n` |
a vector of integers representing the sizes of each non-intersecting population |

`m` |
a vector of integers representing the sample sizes |

`tail` |
whether the p-value should be from the upper or lower tail (options: "upper", "lower") |

`verbose` |
T/F should intermediate messages be printed? |

The probability of getting the k or more (or less if tail="lower") overlaps by chance from the conditional hypergeometric distribution specified by the parameters

1 | ```
pvalchyper(c(1,2), 8, c(12,13,14), c(7,8,9), "upper")
``` |
