In GeneticSubsetter: Identify Favorable Subsets of Germplasm Collections

Description

This function creates a kinship matrix for a set of genotypes. This function is a simplified version of the function "A.mat" in the R package rrBLUP.

Usage

Mat(genos)

Arguments

genos

A matrix of genotypes, where each column is one individual, each row is one marker, and marker values are 1, 0, or -1, or NA, where 0 represents a heterozygous marker, and NA represents missing data. All data in this matrix must be numeric.
