Stability analysis based on Wricke's model

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

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.
