hypergeo.overlap.test: Hypergeometric test of overlap function

In msaul/msaul: Michael C. Saul's Personal R Package

Description

For four character vectors (list1, list2, background1, background2), this function computes a hypergeometric p-value of the overlap. It can test for either overrepresentation or underrepresention.

Usage

hypergeo.overlap.test(list1, list2, background1, background2,
  representation = "over")

Arguments

list1	the first hypergeometric test list
list2	the second hypergeometric test list
background1	the background for the first list
background2	the background for the second list
representation	Test for overrepresentation or underrepresentation? Defaults to "over".

Examples

x = c("one", "two", "three", "four", "five")
y = c("two", "three", "four", "five", "six")
x.bg = c("one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven")
y.bg = c("one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "twelve")
# should return p = 0.003968
hypergeo.overlap.test(x, y, x.bg, y.bg, representation = "over")
