Rowwise Minor Allele Frequency
Computes for each SNP represented by a row of a matrix the frequency of the minor allele.
rowMAFs(x, check = TRUE)
x |
a matrix in which each row represents a SNP and each column a subject, where the genotypes of each SNP are coded by 1 (for the homozygous reference genotype), 2 (heterozygous), and 3 (homozygous variant). NAs are also allowed. |
check |
should it be checked if the matrix contains values differing from 1, 2, and 3?
It is highly recommended to leave |
a vector containing the minor allele frequency of the SNPs represented by x.
