ClueModel: Create a ClueModel object

In simonmoulds/lulcc2: Land Use Change Modelling in R

Description

Methods to create a ClueModel object to supply to allocate.

Usage

ClueModel(observed.lulc, explanatory.variables, predictive.models, time,
  demand, elasticity = 0.1, change.rule, min.elasticity = 0.001,
  max.elasticity = 1.5, min.value, max.value, min.change, max.change,
  max.iteration = 1000, max.difference, cell.area)

Arguments

observed.lulc	an LulcRasterStack
explanatory.variables	an ExpVarRasterStack object
predictive.models	a PredictiveModelList object
time	numeric vector containing timesteps over which simulation will occur
demand	matrix with demand for each land use category in terms of number of cells to be allocated. The first row should be the number of cells allocated to the initial observed land use map (i.e. the land use map for time 0)
elasticity	Initial elasticity value. Default is 0.1
change.rule	numeric vector specifying for each land use whether change is allowed in either direction (0), allowed in the direction of demand only (-1) or not allowed (1)
min.elasticity	Minimum elasticity value. Default is 0.001
max.elasticity	Maximum elasticity value. Default is 1.5
min.value	numeric vector indicating the minimum fraction of each land use in a given cell
max.value	numeric vector indicating the maximum fraction of each land use in a given cell
min.change	numeric vector indicating for each land use the minimum amount of change that is allowed to occur in one time step
max.change	numeric vector indicating for each land use the maximum amount of change that is allowed to occur in one time step
max.iteration	The maximum number of iterations allowed at each time step
max.difference	The maximum allowable difference between demand and allocated area
cell.area	The area of each grid cell in the study region, which should have the same units as the demand
...	additional arguments (none)

Value

A ClueModel object.
