dist_from_biallelic: Genetic distance matrix from biallelic allele counts

In landgraph: Graphs and Covariance for Landscape Genetics

Genetic distance matrix from biallelic allele counts

Description

Computes pairwise squared genetic distances from biallelic (SNP) allele counts. This is a convenience wrapper for dist_from_cov(cov_from_biallelic(Y, N)).

Usage

dist_from_biallelic(Y, N)

Arguments

Y	Numeric matrix of derived-allele counts (populations/individuals in rows, loci in columns).
N	Numeric matrix of haploid sample sizes with the same dimensions as Y. See cov_from_biallelic for flexible N specifications.

Value

A symmetric numeric matrix of pairwise squared distances with zero diagonal. Suitable for use with mlpe or generalized_wishart.

Examples

Y <- matrix(c(2, 1, 0,
              1, 1, 1,
              0, 1, 2), nrow = 3, byrow = TRUE)
N <- matrix(2, nrow = 3, ncol = 3)
dist_from_biallelic(Y, N)
