Roli", "Maintainer": "Altieri Linda ", "Description": "The heterogeneity of spatial data presenting a finite\nnumber of categories can be measured via computation of spatial\nentropy. Functions are available for the computation of the\nmain entropy and spatial entropy measures in the literature.\nThey include the traditional version of Shannon's entropy\n(Shannon, 1948 ),\nBatty's spatial entropy (Batty, 1974\n), O'Neill's entropy\n(O'Neill et al., 1998 ), Li and\nReynolds' contagion index (Li and Reynolds, 1993\n), Karlstrom and Ceccato's entropy\n(Karlstrom and Ceccato, 2002\n),\nLeibovici's entropy (Leibovici, 2009\n), Parresol and Edwards'\nentropy (Parresol and Edwards, 2014 )\nand Altieri's entropy (Altieri et al., 2018,\n). Full references for all\nmeasures can be found under the topic 'SpatEntropy'. The\npackage is able to work with lattice and point data. The\nupdated version works with the updated 'spatstat' package (>=\n3.0-2).", "License": "GPL-3", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.2.3", "NeedsCompilation": "no", "Packaged":
