Get minor-allele-frequency

Calculates minor-allele-frequency (MAF)

Usage

getMAF(geno.matrix, geno.snp = "row", include.het = FALSE)

Arguments

geno.matrix

a matrix or data.frame or sparseMatrix with individuals as columns and markers as rows (geno.snp = "row") or individuals as rows and markers as columns (geno.snp = "col").

geno.snp

if individuals at columns and markers at rows use "row" else if individuals at rows and markers at columns use "col"

include.het

specify if heterozygous calls should be split and added equally to homozygous ref and alt counts (default = FALSE)

Value

a vector containing minor-allele-frequency values
