Initialize an ATN model, following Binzer et al. 2016, Global Change Biology
Description
Initialize an ATN model, following Binzer et al. 2016, Global Change Biology
Usage
create_model_Unscaled(nb_s, nb_b, BM, fw)
Arguments
nb_s |
integer, number of total species. |
nb_b |
integer, number of basal species. |
BM |
float vector, body mass of species. |
fw |
binary adjacency matrix of the food web. |
Details
A model is defined by the total number of species (nb_s), the number of basal species (nb_b), the number of nutrients (nb_n), the body masses (BM) of species, and the adjacency matrix (fw) representing species interactions.
Value
An object of class ATN (Rcpp_parameters_prefs).
