gxe_analysis_multiple: Two-Way ANOVA for Genotype x Environment Interaction with Multiple Traits

Description

This function performs a two-way ANOVA to analyze genotype and environment interactions for multiple traits, including replication effects. It provides separate ANOVA results for each specified trait in the dataset.

Usage

gxe_analysis_multiple(
  data,
  genotype_col,
  environment_col,
  replication_col,
  trait_cols
)

Value

A list containing ANOVA results for each trait.

Arguments

data

A data frame containing the dataset with required columns.

genotype_col

Character. Name of the genotype column.

environment_col

Character. Name of the environment column.

replication_col

Character. Name of the replication column.

trait_cols

A vector of trait column names to analyze.
