In nprcgenekeepr: Genetic Tools for Colony Management

Calculate mean kinship for each animal in a kinship matrix

Description

Part of Genetic Value Analysis

Usage

meanKinship(kmat)

Arguments

kmat	a numeric matrix of pairwise kinship coefficients. Animal IDs are the row and column names.

Details

The mean kinship of animal i is

MK_i = \Sigma f_ij / N

, in which the summation is over all animals, j, including the kinship of animal i to itself.

Value

A named numeric vector of average kinship coefficients for each animal ID. Elements are named with the IDs from the columns of kmat.
