Regression-based stability analysis using the Eberhart and Russell (1966) model.
ge_reg(.data, env, gen, rep, resp, verbose = TRUE)
The dataset containing the columns related to Environments, Genotypes, replication/block and response variable(s)
The name of the column that contains the levels of the environments.
The name of the column that contains the levels of the genotypes.
The name of the column that contains the levels of the replications/blocks
The response variable(s). To analyze multiple variables in a
single procedure use, for example,
Logical argument. If
An object of class
ge_reg with the folloing items for each variable:
The data with means for genotype and environment combinations and the environment index
The analysis of variance for the regression model.
The estimated coefficients of the regression model.
