In geneticae: Statistical Tools for the Analysis of Multi Environment Agronomic Trials

Robust AMMI Model

Description

Fits a classical or robust Additive Main effects and Multiplicative Interaction (AMMI) model.

Usage

rAMMIModel(
  Data,
  genotype = "gen",
  environment = "env",
  response = "Y",
  rep = NULL,
  Ncomp = 2,
  type = "AMMI"
)

Arguments

Data	a dataframe with genotypes, environments and the phenotypic trait.
genotype	column name containing genotypes.
environment	column name containing environments.
response	column name containing the phenotypic trait.
rep	column name containing replications. If provided, means are calculated.
Ncomp	number of principal components to retain.
type	method for fitting: '"AMMI"', '"rAMMI"', '"hAMMI"', '"gAMMI"', '"lAMMI"' or '"ppAMMI"'.
