ge_effects: Genotype-environment effects

In metan: Multi Environment Trials Analysis

Genotype-environment effects

Description

This is a helper function that computes the genotype-environment effects, i.e., the residual effect of the additive model

Usage

ge_effects(.data, env, gen, resp, type = "ge", verbose = TRUE)

Arguments

.data	The dataset containing the columns related to Environments, Genotypes, replication/block and response variable(s).
env	The name of the column that contains the levels of the environments. The analysis of variance is computed for each level of this factor.
gen	The name of the column that contains the levels of the genotypes.
resp	The response variable(s). To analyze multiple variables in a single procedure a vector of variables may be used. For example resp = c(var1, var2, var3).
type	The type of effect to compute. Defaults to "ge", i.e., genotype-environment. To compute genotype plus genotype-environment effects use type = "gge".
verbose	Logical argument. If verbose = FALSE the code will run silently.

Value

A list where each element is the result for one variable that contains a two-way table with genotypes in rows and environments in columns.
