Usage
findLoops(ptree)
Arguments
ptree
a list of lists forming a pedigree tree as constructed by
createPedTree(ped) where ped is a standard pedigree dataframe.
Value
A named list of logical values where each named element is
named with an id from ptree. The value of the list element
is set to TRUE if the id has a loop in the pedigree.
Loops occur when an animal's sire and dam have a common ancestor.
Details
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.
