Inbreeding coefficient

Description

Computes the standard inbreeding coefficient (F). This is the probability that two alleles on a locus are identical by descent (Falconer and Mackay 1996, Wright 1922), calculated from the genealogical coancestry matrix (Malécot 1948).

A dataframe containing the pedigree. Individual (id), maternal (dam), and paternal (sire) identities are mandatory columns.
