## 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.
