stab_kang function

Stability Kang Function

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.

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

Examples

data(ge_data)
YieldKang <-
     stab_kang(
            .data = ge_data
          , .y    = Yield
          , .rep  = Rep
          , .gen  = Gen
          , .env  = Env
      )
YieldKang
