makeGRM: makeGRM function

In jeanlucj/AlfSimHlpR: Functions added to AlphaSimR to simplify simulating breeding schemes

Description

function to make a genomic relationship matrix to be used to analyze the phenotypic records

Usage

makeGRM(records, bsp, SP)

Arguments

records	The breeding program records object. See fillPipeline for details
bsp	The breeding scheme parameter list
SP	The AlphaSimR SimParam object. Needed to pull the SNP genotypes

Details

records maintains the phenotypic and genotypic records across years and stages. For GEBV analysis, you need the GRM of these individuals. makeGRM assumes the first phenotyping stage (records[[2]]) has all individuals that have been phenotyped. The GRM also includes the unphenotyped new F1 individuals in records[[1]]

Value

A genomic relationship matrix

Examples

grm <- makeGRM(records, bsp, SP)
