Get Genetic Value Genotype data structure for reportGV function.

Extracts genotype data if available otherwise NULL is returned.

Usage

getGVGenotype(ped)

Arguments

ped

the pedigree information in datatable format

Value

A data.frame with the columns id, first, and second extracted from a pedigree object (a data.frame) containing genotypic data. If the pedigree object does not contain genotypic data the NULL is returned.

Examples

## We usually defined `n` to be >= 5000
library(nprcgenekeepr)
ped <- nprcgenekeepr::lacy1989Ped
allelesNew <- geneDrop(ped$id, ped$sire, ped$dam, ped$gen,
                      genotype = NULL, n = 50, updateProgress = NULL)
genotype <- data.frame(id = ped$id,
