Agents settle landscape based on conspecific attraction This function acts iteratively to allow agents to settle the landscape selecting randomly from cells defined as available based on proximity to previously settled cells. The first agent settles the landscape completely randomly. Instanciation as a function allows the entire ABM to be run an arbitray number of times (see 'reps' below) in order to generate a sampling distribution of apparent selections generated by the model.
1 | settle.con(radius, ID.mat, hab.mat, n.individ, A.coef, ...)
|
radius |
Sets how many cells away from the occupied cells should be included in the "neighborhood". Passed to 'neighbors'. |
ID.mat |
A matrix of the same size as the simulated landscape but with the value of each cell corresponding to it's cell ID. Passed to 'neighbors'. |
hab.mat |
The matrix containing the "grown" habitats enumerated by the strength of preference (e.g., the output from pref.strength, not convert.cell.) Note that which hab.mat to use (i.e., which preference strength to use) is arbitrary for the null model, but the choice must match the 'A.coef' supplied (below). |
n.individ |
The number of individuals included in the ABM. |
A.coef |
The habitat preference parameter that matches the hab.mat supplied. This is the "key" that allows the function to interpret each cell of the matrix as either "Habitat A" or "Habitat B". |
... |
Additional arguments as necessary. |
The proportion of simulated settled locations located in Habitat A as well as the raw locations for each simulation run
