Details

The DESCRIPTION file: tools:::Rd_package_DESCRIPTION("ShapePattern") tools:::Rd_package_indices("ShapePattern") This package combines the legacy functionality of package PatternClass and package ShapePattern and sets the environment for continuing to contribute to shape and pattern analyses. Eventually, package PatternClass will be archived (please point to this package to maintain functionality). Functions are provided to perform (1) ShrinkShape, a spatial decomposition by iterative shrinking of planar shapes (ploygons); (2) PatternClass, a tool for computing and visualizing statistical differences between class-level landscape maps; (3) Patternbits, a means for producing probability distributions for the most elemental hyper-local pattern elements in a binary landscape map and using Kullback-Leibler divergence to assess similarity and differnece between two such distributions; (4) CAR 2D simulation of stationary and isotropic landscape patterns, and (5) a tool for computing raster zone (patch) porosity.
