SexualSelection

Sexual Conflict

Description

Number of species in each of two taxa in closely related taxon pairings and the difference between the two groups. One taxon has multiple matings (polyandrous.species) and one has only single matings (monandrous.species).

Format

A data frame with 25 observations on the following 4 variables.

polyandrous.species: a numeric vector
monandrous.species: a numeric vector
difference: a numeric vector
taxon.pair: identifier

Examples

SexualSelection

histogram(~ difference, SexualSelection, n = 20)

hist(SexualSelection$difference, breaks = 20)

# Calculate the number of tests and the number of negative tests
(n <- length(SexualSelection$difference))
(n.neg <- sum(SexualSelection$difference < 0))

2 * pbinom(q = n.neg, size = n, prob = 0.5)

# With a binomial test
binom.test(n.neg, n, p = 0.5)
