A utility script to recalculate the frequency of the homozygous alternate SNP by locus after some populations have been deleted
Source:R/utils.recalc.freqhomsnp.r
utils.recalc.freqhomsnp.Rd
The locus metadata supplied by DArT has FreqHomSnp included, but the frequency of the homozygous alternate will change when some individuals are removed from the dataset.
Details
This script recalculates the FreqHomSnp and places these recalculated values in the appropriate place in the genlight object.
Note that the frequency of the homozygote alternate SNPS is calculated from the individuals that could be scored.
