Fij_core {purgeR}

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.
