Description

An AD model with row and column effects included is used for controlling field variation. This model is analyzed by the REML approach. The data set can be irregular or missing but the field layout should be rectangular. It can analyze any genetic mating designs and data including F1, F2, or F3 with parents..

Usage

1
ad4rc.reml(Y, Ped, Row = NULL, Col = NULL)

Arguments

Y

A data matrix for one or more traits

Ped

A pedigree matrix including Environment, Female1, Male1, Female2, Male2, Generation is required.

Row

A vector for field rows. It can be default.

Col

A vector for field colums.It can be default.

Details

If only row or column vector is included, this is equivallent to an AD model with block effects.

Value

Return a list of results: estimated variance components, estimated fixed effects, and predicted random effects
