Thennarasu function

Thennarasu's stability statistics

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

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.

Returns

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.

Examples

library(metan)
out <- Thennarasu(data_ge, ENV, GEN, GY)
print(out)
