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.
