Details

Part of Pedigree Sampling From PedigreeSampling.R 2016-01-28

Contains functions to build pedigrees from sub-samples of genotyped individuals.

The goal of sampling is to reduce the number of inbreeding loops in the resulting pedigree, and thus, reduce the amount of time required to perform calculations with SIMWALK2 or similar programs.

This function uses only id, sire, and dam columns.

Examples

# \donttest{
library(nprcgenekeepr)
exampleTree <- createPedTree(nprcgenekeepr::examplePedigree)
exampleLoops <- findLoops(exampleTree)
# }
