%description
Partitions the phenotypic variance of a plastic trait, studied through its
reaction norm. The variance partition distinguishes between the variance
arising from the average shape of the reaction norms (V_Plas) and the
(additive) genetic variance . The latter is itself separated into an
environment-blind component (V_G/V_A) and the component arising from
plasticity (V_GxE/V_AxE). The package also provides a way to further
partition V_Plas into aspects (slope/curvature) of the shape of the
average reaction norm (pi-decomposition) and partition V_Add
(gamma-decomposition) and V_AxE (iota-decomposition) into the impact of
genetic variation in the reaction norm parameters. Reference: de
Villemereuil & Chevin (2025) <doi:10.32942/X2NC8B>.
