kronecker_delta: This function returns the kronecker operator for two loci.

In dyerlab/gstudio: Tools Related to the Spatial Analysis of Genetic Marker Data

This function returns the kronecker operator for two loci.

Description

This is a quick utility function that provides the Kronecker operators for a pair of loci

Usage

kronecker_delta(locus1, locus2)

Arguments

locus1	An object of type 'locus'
locus2	An object of type 'locus'

Value

a named vector of kronecker products.

Note

The Kronecker operator is a vector consisting of values related to the similarity of alleles among two loci. For the genotypes AiAj and AkAl the Kronecker deltas are =0 of the subscripted alleles are different and =1 if they are the same (e.g., dij = 0 if heterozygote, = 1 if homozygote)
