snakes: Snakes data

Description

Genetic covariance matrices for six genetic traits of two female garter snake populations, one from a coastal and the other from inland site in northern California. The data set was initially studied by Phillips and Arnold (1999).

Usage

data(snakes)

Format

List format of 3 components.

snakes[[1]]

sample genetic covariance matrix for the inland population, obtained.

snakes[[2]]

sample genetic covariance matrix for the coastal population.

snakes[[3]]

vector of sample sizes, respectively for inland and coastal samples.

Details

Both genetic variance-covariances are obtained on six traits of the snakes.
