clue: CLUE

In simonmoulds/lulcc2: Land Use Change Modelling in R

Description

Allocate land use change using the CLUE algorithm.

Usage

clue(lu0.vals, regr, demand, elasticity, change.rule, min.elasticity,
  max.elasticity, min.change, max.change, min.value, max.value,
  max.iteration, max.difference, cell.area, ncell, ncode)

Arguments

lu0.vals	matrix containing non-NA values from lu0
regr	matrix containing...
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 land use map, the second row should be the number of cells to allocate in the subsequent time point
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.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
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
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
ncell	number of cells considered for change (equal to the length of lu0.vals
ncode	number of land use categories under consideration
...	additional arguments (none)

Value

numeric vector with updated land use values.
