Stability analysis based on Wricke's model

Description

The function computes the ecovalence (Wricke, 1965) for stability analysis.

Usage

ecovalence(.data, env, gen, rep, resp, verbose = TRUE)

Arguments

`.data`	The dataset containing the columns related to Environments, Genotypes, replication/block and 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.
`rep`	The name of the column that contains the levels of the replications/blocks.
`resp`	The response variable(s). To analyze multiple variables in a single procedure use, for example, `resp = c(var1, var2, var3)`.
`verbose`	Logical argument. If `verbose = FALSE` the code will run silently.

Value

An object of class ecovalence containing the results for each variable used in the argument resp.
