Annicchiarico: Annicchiarico's genotypic confidence index

Description

Stability analysis using the known genotypic confidence index (Annicchiarico, 1992).

Usage

Annicchiarico(.data, env, gen, rep, resp, prob = 0.25, 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).

prob

The probability of error assumed.

verbose

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

Value

A list where each element is the result for one variable and contains the following data frames:

  • environments Contains the mean, environmental index and classification as favorables and unfavorables environments.

  • general Contains the genotypic confidence index considering all environments.

  • favorable Contains the genotypic confidence index considering favorable environments.

  • unfavorable Contains the genotypic confidence index considering unfavorable environments.
