ibs {QTLRel}

Estimate Jacquard condensed identity coefficients

Description

Estimate Jacquard condensed identity coefficients by identity-by-state (IBS) from genotypic data.

Usage

ibs(x)

Arguments

x

Genotype data with genotypes ("AA", "AB", "BB", or, 1, 2, 3) and without missing data, or probabilities for these genotypes (e.g., obtained by using genoProb). In case of genotype data, rows represent individuals and columns represent SNPs.

Value

A matrix G with G[,j] being the j-th Jacquard identity coefficients.

Note

Currently only support the two-allele data.
