Genealogy subset

Description

Creates an object of class GLgen from an existing GLgen object by selecting specified individuals.

Usage

gen.branching( gen, pro = 0, ancestors = gen.founder(gen), bflag = 0)

Arguments

`gen`	An object of class GLgen obtained with gen.genealogy, gen.lineages or gen.branching. Required.
`pro`	Vector of proband id numbers to be included. Default is 0, which will select all individuals without children.
`ancestors`	Vector of ancestors id numbers to be included. Default includes all founders in the original GLgen object.
`bflag`	If set to 0 (default and recommended), probands and founders are filtered to quicken the calculations.

Value

returns a GLgen object

Note

Note that if there are no links between some probands and ancestors, these ids will not be included.

Examples

data(geneaJi) 
genJi<-gen.genealogy(geneaJi)
genJi_part<-gen.branching(genJi,pro=c(2,28)) 

# Plots of original genealogy and of the branched version
layout(matrix(1:2,c(1,2),byrow=TRUE))
gen.graph(genJi) 
mtext("Original", line=2, cex=1.2)
gen.graph(genJi_part) 
mtext("Branched tree\nfor individuals 2 and 28", line=1, cex=1.2)
