Description

An R function to generate an ADAA model simulated data set with given parameters and data structure.

Usage

1
adaa.simudata(Y, Ped, v, b, SimuNum = NULL)

Arguments

Y

A matrix of trait with one or more than one trait.

Ped

A pedigree matrix including Environment, Female, Male, Generation, with or without block is required. So the matrix should include either 4 columns or 5 columns.

v

A vector of preset variance components.

b

A vector of present fixed effects.

SimuNum

The number of simulations. The default number is 200.

Value

Return a simulated data set which is a matrix.
