algo9: Generate autocorrelated data

In aslez/maup: Autocorrelated surfaces and random zoning systems

Description

algo9 generates a valued raster with a specified degree of autocorrelation.

Usage

algo9(x, mori, tol = 1/100, maxIter = 10000, print_out = TRUE)

Arguments

x	an object of class Raster or a numeric vector depicting the dimensions of a new raster.
mori	a numeric scalar indicating the desired degree of autocorrelation. Autocorrelation is measured using Moran's I.
tol	numeric indicating tolerance for convergence.
maxIter	numeric indicating the maximum number of observations.
print_out	logical indicating whether or not to print the iteration number. The default is TRUE.

Details

Implements the algorithm outlined by Goodchild (1980).

Value

algo9 returns a Raster class object representing a randomly generated surface with a specificed degree of autocorrelation.
