Genotype-environment means — ge

Computes genotype-environment interaction means

Usage

ge_means(.data, env, gen, resp)

Arguments

.data: The dataset containing the columns related to Environments, Genotypes, and the response variable(s).
env: The name of the column that contains the levels of the environments.
gen: The name of the column that contains the levels of the genotypes.
resp: The response variable(s). To analyze multiple variables at once, a vector of variables may be used. For example resp = c(var1, var2, var3). Select helpers are also allowed.

Value

A list where each element is the result for one variable containing:

ge_means: A two-way table with the means for genotypes (rows) and environments (columns).
gen_means: A tibble with the means for genotypes.
env_means: A tibble with the means for environments.
