Usage

Arguments

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.
Value
A matrix of kinship values between genotypes.
