stab_kang {stability}

Stability Kang Function

Description

Performs a stability analysis based on the Kang (1988) criteria. Kang nonparametric stability (ranksum) uses both "trait single value" and stability variance (Shukla, 1972), and the genotype with the lowest ranksum is commonly the most favorable one.

Usage

stab_kang(.data, .y, .rep, .gen, .env)

## Default S3 method:
stab_kang(.data, .y, .rep, .gen, .env)

Arguments

.data

data.frame

.y

Response Variable

.rep

Replication Factor

.gen

Genotypes Factor

.env

Environment Factor
