check_mafs: Check the 'mafs', the minor allele frequencies.

In richelbilderbeek/plinkr: Interface to PLINK

Check the mafs, the minor allele frequencies.

Description

Check the mafs, the minor allele frequencies, will stop if these are invalid.

Usage

check_mafs(mafs)

Arguments

mafs

one or more minor allele frequencies. These allele frequencies must be ordered decreasingly, i.e. the MAF is at the first position, where the even rarer alleles are at the second and third positions. Note that PLINK cannot handle triallelic nor quadallelic SNPs: PLINK will give a warning that it is setting the rarest alleles to missing.
