In syanco/checkyourself: Simulates a simple agent-based species distribution model

Description

A function to simulate a single individual moving with varying mixtures of preference for habitat and/or short steps.

Usage

chooseLoc(
  hab.prob,
  pd.rate,
  steps,
  lambda,
  coef.d,
  coef.r,
  blank.rast,
  matsize,
  ...
)

Arguments

hab.prob	matrix, the habitat matrix with cell values representing the habitat-only probabilities (uncorrected for the mixing proportions with distance). Typically the second element of the list returned by simlandscapes.
pd.rate	numeric, the probability of returning to the central place to "deliver prey" to nest/den/etc. on any given step (given the agent isnot currently located at the central place.) Must be <1.
steps	integer, the number of steps the agent should take
lambda	numeric, the strength of the declining exponental function that controls how "reluctant" the agent is to move large distances. Must be <1.
coef.d	numeric, can be factor or proportion representing the relative strength of the preference to move short steps compared to the strength of the preference for habitat.
coef.r	numeric, can be factor or proportion representing the relative strength of the preference for habitat compared to the strength of the preference for short steps.
matsize	integer, the size in number of cells of one side of the square matrix on which the simulation is being run.
...

Value

Returns the list of positions for the simulated individual.
