View source: R/ge_stats.R



ge_stats() computes parametric and non-parametric stability statistics given a data set with environment, genotype, and block factors.


ge_stats(.data, env, gen, rep, resp, verbose = TRUE, prob = 0.05)



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, resp = c(var1, var2, var3).


Logical argument. If verbose = FALSE the code will run silently.


The probability error assumed.


The function computes the statistics and ranks for the following stability indexes.


An object of class ge_stats which is a list with one data frame for each variable containing the computed indexes.
