A utility script to recalculate the OneRatioRef, OneRatioSnp, PICRef, PICSnp, and AvgPIC by locus after some individuals or populations have been deleted.
Source:R/utils.recalc.avgpic.r
utils.recalc.avgpic.Rd
The locus metadata supplied by DArT has OneRatioRef, OneRatioSnp, PICRef, PICSnp, and AvgPIC included, but the allelic composition will change when some individuals,or populations, are removed from the dataset and so the initial statistics will no longer apply. This script recalculates these statistics and places the recalculated values in the appropriate place in the genlight object.
Details
If the locus metadata OneRatioRef|Snp, PICRef|Snp and/or AvgPIC do not exist, the script creates and populates them.
