Fij_core: Partial inbreeding coefficient (core function)

In purgeR: Inbreeding-Purging Estimation in Pedigreed Populations

Partial inbreeding coefficient (core function)

Description

Computes partial inbreeding coefficients, Fi(j). A coefficient Fi(j) can be read as the probability of individual i being homozygous for alleles derived from ancestor j

Usage

Fij_core(ped, ancestors, ancestors_idx, Fi, mapa, ncores = 1, genedrop, seed)

Arguments

ped	A dataframe containing the pedigree. Individual (id), maternal (dam), and paternal (sire) identities are mandatory columns.
ancestors	Vector of the identities to be assumed as founder ancestors.
ancestors_idx	Index of ancestors.
Fi	Vector of inbreeding coefficients.
mapa	Map of ancestors
ncores	Number of cores to use for parallel computing (default = 1)
genedrop	Enable genedrop simulation
seed	Sets a seed for the random number generator.

Value

A matrix of partial inbreeding coefficients. Fi(j) values can thus be read from row i and column j.
