Performs a stability analysis based on Thennarasu (1995) statistics.
Usage
Thennarasu(.data, env, gen, resp, verbose = TRUE)
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.
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.
