In GENLIB: Genealogical Data Analysis

gen.findFounders

R Documentation

Find common founder ancestors

Description

Returns all the ancestors that are founders for specified individuals in the genealogy.

Usage

gen.findFounders(gen, individuals, NbProcess=parallel::detectCores()-1)

Arguments

`gen`	An object of class GLgen obtained with gen.genealogy, gen.lineages or gen.branching. Required.
`individuals`	Vector of individual id numbers for which to find the founders. Required
`NbProcess`	Number of processes to use when running this function. Default=parallel::detectCores()-1

Value

A vector of integers

Note

Uses slave processes to make the search faster. Those slave processes launch the function gen.getFoundersMPI.

Examples

data(geneaJi) 
genJi<-gen.genealogy(geneaJi) 
gen.founder(genJi)
gen.findFounders(genJi, individuals=c(1,29), NbProcess = 1)

data(genea140) 
gen140<-gen.genealogy(genea140) 
gen2<-gen.branching(gen140,pro=c(409033,408728)) 
# 615 founders in genealogy of #409033 and #408728
all_founders<-gen.founder(gen2) 
length(all_founders)


all_commonFounders<-gen.findFounders(gen140, individuals=c(409033,408728), NbProcess = 1)
length(all_commonFounders) # 127 founders common to #409033 and #408728
