ShapePattern-package | Tools for Analyzing Shapes and Patterns
build.lut | Bias correction lookup table (LUT) builder based on simulations.
buildsurfs | Build an array of surfaces across compositional and configuration analysis space.
CARsimu | This function simulates an image using a FFT implementation of a Conditional Autoregressive (CAR) model.
data | This is a generic data environment that provides some demo data and control functionality.
doubleplotter | A comparison of two maps based on their empirical (null) distributions for a class-focused pattern metric
findcol | An internal utility that identifies that identifies the appropriate column of the Whittle correction matrix.
findrow | An internal utility that identifies that identifies the appropriate row of the Whittle correction matrix.
imaks | Draws a matrix in the proper orientation, as it it were a raster landscape.
KLPQ | Computes and returns the Kullback-Leibler divergence between two probability distributions
patternbits | Decompose a binary landscape (grid) to count its pattern elements
porosity | Compute the porosity of raster zones (patches)
ShapePattern | Tools for Analyzing Shapes and Patterns
singlemap | Process a single binary map
singleplotter | Depict the empirical (null) distribution for class-focused pattern metrics.
ssr | Decompose a planar shape (polygon) to produce area, perimeter, and number of parts spectra
surfplot | Produce graphic plots providing class-focused pattern metric context for a landcape map
wi | An internal utility that helps with the Whittle estimation.
