simul.pedigree: Simulation of pedigree structure
In synbreed: Framework for the Analysis of Genomic Prediction Data using R

Description Usage Arguments Details Value Author(s) See Also Examples

This function can be used to simulate a pedigree for a given number of generations and individuals. Function assumes random mating within generations. Inbred individuals may be generated by chance.

1	simul.pedigree(generations = 2, ids = 4, animals=FALSE,familySize=1)

`generations`	`integer`. Number of generations to simulate
`ids`	`integer` or vector of integers. Number of genotypes in each generation. If length equal one, the same number will be replicated and used for each generation.
`animals`	`logical`. Should a pedigree for animals be simulated (no inbreeding)? See 'Details'.
`familySize`	`numeric`. Number of individuals in each full-sib family in the last generation.

If animals=FALSE, the parents for the current generation will be randomly chosen out of the genotypes in the last generation. If Par1 = Par2, an inbreed is generated. If animal=TRUE, each ID is either sire or dam. Each ID is progeny of one sire and one dam.

An object of class pedigree with N=sum(ids) genotypes.
