kinship: kinship function

In wolfemd/predCrossVar: Prediction of family genomic variances and covariances

Description

Function to create additive and dominance genomic relationship matrices from biallelic dosages.

Usage

kinship(M, type)

Arguments

M	dosage matrix. Assumes SNPs in M coded 0, 1, 2 (requires rounding dosages to integers). M is Nind x Mrow, numeric matrix, with row/columanes to indicate SNP/ind ID.
type	string, "add" or "dom". type="add" gives same as rrBLUP::A.mat(), i.e. Van Raden, Method 1. type="dom" gives classical parameterization according to Vitezica et al. 2013.

Value

square symmetic genomic relationship matrix

Examples

K<-kinship(M,"add")
