coefficient_of_determination

<code>coefficient_of_determination</code> calculate variance of a genotype across environments.

Tools to calculate stability indices with parametric,
non-parametric and probabilistic approaches. The basic data format requirement for 'toolStability' is a data frame with 3 columns including numeric trait values, genotype,and environmental labels. Output format of each function is the dataframe with chosen stability index for each genotype.
Function "table_stability" offers the summary table of all stability indices in this package.
This R package toolStability is part of the main publication:
