Matrix of Opposing Homozygotes

Description

Creates a matrix of opposing homozygotes from the genotype matrix.

Usage

ohg(genotypeMatrix)

Arguments

genotypeMatrix

matrix genotype (Data should be numeric. Use 0, 1 and 2 respectively for AA, AB and BB. Use 9 for missing data)

Value

Returns a square matrix (sample X sample) with the pairwise counts of opposing homozygotes.

Note

This function can be slow with a large data set. The fast version of this function will be available after publish of the related manuscript.
