In keepsimpler/perturbEcol: Simulation of ecological dynamic systems under environmental perturbations

Description

perturbEcol simulates the dynamics of networked ecological systems that undergo environmental perturbations such as climate change etc.

The simulation model is implemented as S4 class with the following slots:

• main = function(time, init, params, ...): a function holding the main equations of the model, such as ODE, SDE.

• times: vector of time steps or vector with three named values from, to, by specifying the simulation time steps.

• init: initial state (start values) of the simulation. This is a named vector of state variables such as species abundances.

• params: a list of model parameters whose values would be changed by iterated perturbations.

• perturb = function(params, ...): a function describing(?) the perturbation or pressure by environments on ecological systems. The results of perturbations are the changing of model parameters.

• perturbNum: the number of repeated perturbations.

• solver = function(main, times, init, params, perturb, perturbNum, ...): a function specifying the numerical algorithm of simulation. The algorithms model the dynamics of ecological systems undergoing environmental perturbations.

• out: the output of simulation.
