Arguments

Pedig

Pedigree with column Indiv and the column specified in parameter from.

from

Column name. From each cohort specified in this column (e.g. year of birth), the number of individuals specified in parameter each is sampled. If a cohort contains less individuals, then all individuals are chosen.

each

Number of individuals to be sampled from each cohort.
