Fills in any missing values for gamma so that fish feeding on a resource spectrum described by the power law \(\kappa w^{-\lambda}\) achieve a feeding level \(f_0\). Only for internal use.
get_gamma_default(params)A vector with the values of gamma for all species
A MizerParams object
See the Search Volume Coefficient section of the "Calculation of Default Parameter Values" vignette for the mathematical derivation.
The available energy is measured with the predation part of mizer's own
encounter rate, mizerEncounter(). It is a property of the species
parameters and of the resource power law rather than of the model's dynamics,
so external encounter and contributions registered with other_encounter()
(including component encounter functions) are excluded. The measurement also
deliberately does not go through the extension dispatch chain, nor through an
encounter function registered with setRateFunction().
Other functions calculating defaults:
get_f0_default(),
get_h_default(),
get_ks_default()
