map_ancestors

Creates a logical matrix that indicates whether an individual i (in columns) is ancestor of other j (in rows)
For example, matrix[, 1] will indicate descendants of id = 1
And matrix[1, ] indicates ancestors of id = 1

Inbreeding-purging analysis of pedigreed populations, including the computation of the inbreeding coefficient, partial, ancestral and purged inbreeding coefficients, and measures of the opportunity of purging related to the individual reduction of inbreeding load.
In addition, functions to calculate the effective population size and other parameters relevant to population genetics are included.
