In wolfemd/genomicMateSelectR: Genomic Mate Selection

Filter a dosage matrix by a minor allele frequency

Description

filter a dosage matrix by minor allele frequence. get a vector of allele frequences from a dosage matrix

Usage

maf_filter(M, thresh)

Arguments

M	dosage matrix. Assumes SNPs in M coded 0, 1, 2 (requires rounding dosages to integers). M is Nind x Mrow, numeric matrix, with row/columanes to indicate SNP/ind ID
thresh	threshold value. Columns of M with maf<thresh will be removed

Value

dosage matrix potentially with columns removed
