Species: Creates a new species

In andrechalom/TWoLifR: An R library For Agent-Based Simulations of Demography in Heterogeneus Landscapes

Description

Currently, every simulation contains a single species that must be created using this function.

Usage

Species(landscape, birth.rate = 1, death.rate = 0.1, incl.birth = 5,
  incl.death = 0, radius = 5, matrix.death = 10, move.rate = 1,
  step = 1, visual.angle = base::pi/4)

Arguments

landscape	the Landscape in which this species lives
birth.rate	the intrinsic birth rate of the species
death.rate	the intrinsic death rate of the species
incl.birth	the slope in which the birth rate decreases with increasing density
incl.death	the slope in which the death rate increases with increasing density
radius	the perception radius of the species. Setting this to zero will turn off all the neighbor detection, so only use radius=0 if you really want exponential growth!
matrix.death	a constant multiplying the death rate in non-habitat patches (Currently unimplemented!)
move.rate	the intrinsic movement rate of the species
step	the length of the step for each movement
visual.angle	currently, controls how much the movement orientation changes between steps

Details

Use this class to set up new species. Currently, the individuals only interact with individuals of the same species (that is, multiple species on the same landscape are totally independent).

WARNING

Every time the function Species is called, a new species is created and pushed to the landscape's species list.
