# Thennarasu: Thennarasu's stability statistics In metan: Multi Environment Trials Analysis

## Description

Performs a stability analysis based on Thennarasu (1995) statistics.

## Usage

 1 Thennarasu(.data, env, gen, 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. 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 Thennarasu, which is a list containing the results for each variable used in the argument resp. For each variable, a tibble with the columns GEN, N1, N2, N3 and N4 is returned.
