Interaction matrix

Usage

fun_int_mat(n_species, alpha, min_alpha, max_alpha, interaction_type)

n_species: Integer. Number of species in a metacommunity.
alpha: Numeric matrix. Species interaction strength. Enabled if interaction_type = "constant". Default 0.
min_alpha: Numeric. Minimum value of a uniform distribution generating interaction strength. Enabled if interaction_type = "random". Default NULL.
max_alpha: Numeric. Maximum value of a uniform distribution generating interaction strength. Enabled if interaction_type = "random". Default NULL.
interaction_type: Character. "constant" or "random". "constant" assumes the unique interaction strength of alpha for all pairs of species. "random" draws random numbers from a uniform distribution with min_alpha and max_alpha.
