adjusted_coefficient_of_variation: Adjusted coefficient of variaiton

In toolStability: Tool for Stability Indices Calculation

Adjusted coefficient of variaiton

Description

adjusted_coefficient_of_variation calculate variance of a genotype across environments.

Usage

adjusted_coefficient_of_variation(data, trait, genotype, environment)

Arguments

data	a dataframe containing trait, genotype and environment.
trait	colname of a column containing a numeric vector of interested trait to be analyzed.
genotype	colname of a column containing a character or factor vector labeling different genotypic varieties
environment	colname of a column containing a character or factor vector labeling different environments

Details

Adjusted coefficient of variaiton (Doering and Reckling, 2018) is calculatd based on regression function. Variety with low adjusted coefficient of variation is considered as stable. Equation of adjusted coefficient of variation can be found in vignette file.

Value

a data table with adjusted coefficient of variation
