I'm attempting to do a PCA and a DAPC on genomic data, 186 individuals
spread over 11 putative populations, with just over 4000 loci. I have
converted the data to a genlight object. I'm wondering, I know that I have
some missing data (markers are present in at least 65% of individuals). In
the Adegent manual it specifies that missing data could bias results. How
do I know if I have too much missing data, or should I just get rid of all
the loci that have missing values before doing the analysis?
