<br>
OK I think I got it. So:<br>
- I can't remember how I built the eHGDP dataset, but it's an easy task<br>
- I don't know if the data you're looking for is publicly available<br>
- assuming you find it, there are two ways to get a genpop object:<br>
#1: from individual data with pop info: read data in (read.csv /<br>
read.table), use df2genind (be patient there, that'll take a while),<br>
then genind2genpop<br>
<br>
#2: from population data (allele counts): read data in (read.csv /<br>
read.table), use the genpop() constructor to make the data a genpop<br>
object; I think this is documented in the basics tutorial, but<br>
definitely also in ?genpop<br>
