This collection provides tools for: (1) the spatial\ndecomposition of planar shapes using 'ShrinkShape' to\nincrementally shrink shapes to extinction while computing area,\nperimeter, and number of parts at each iteration of shrinking;\nthe spectra of results are returned in graphic and tabular\nformats (Remmel 2015) , (2) simulating\nlandscape patterns, (3) provision of tools for estimating\ncomposition and configuration parameters from a categorical\n(binary) landscape map (grid) and then simulates a selected\nnumber of statistically similar landscapes. Class-focused\npattern metrics are computed for each simulated map to produce\nempirical distributions against which statistical comparisons\ncan be made. The code permits the analysis of single maps or\npairs of maps (Remmel and Fortin 2013)\n, (4) counting the number of\neach first-order pattern element and converting that\ninformation into both frequency and empirical probability\nvectors (Remmel 2020) , and (5)\ncomputing the porosity of raster patches\n. NOTE: This is a consolidation of\nexisting packages ('PatternClass', 'ShapePattern') to begin\nwarehousing all shape and pattern code in a common package.\nAdditional utility tools for handling data are provided and\nthis package will be added to as more tools are created,\ncleaned-up, and documented. Note that all future developments\nwill appear in this package and that 'PatternClass' will\neventually be archived.", "License": "GPL-3", "LazyData": "true", "LazyDataCompression": "xz", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-09 06:59:16 UTC", "User": "root" }, "Author": "Tarmo K.
