Format

A 12 x 12 matrix.

Examples

params <- newMultispeciesParams(NS_species_params_gears,
                                interaction = NS_interaction)
#> ℹ No `a` column so using a = 0.01 in w = a l^b, with w in g and l in cm.
#> ℹ No `b` column so using the isometric default b = 3 in w = a l^b.
#> ℹ No h provided for some species, so using age at maturity to calculate it.
#> ℹ Because you have n != p, the default value for `h` is not very good.
#> ℹ Because the age at maturity is not known, I need to fall back to using
#> von Bertalanffy parameters, where available.
#> ℹ Using z0 = z0pre * w_inf ^ z0exp for calculated z0 values.
#> ℹ Using f0, h, lambda, kappa and the predation kernel to calculate gamma.
