bnspatial (version 0.9)

Spatial Implementation of Bayesian Networks and Mapping

Description

Package for the spatial implementation of Bayesian Networks and mapping in geographical space. It makes maps of expected value (or most likely state) given known and unknown conditions, maps of uncertainty measured as both coefficient of variation or Shannon index (entropy), maps of probability associated to any states of any node of the network. Some additional features are provided as well, such as parallel processing options, data discretization routines and function wrappers designed for users with minimal knowledge of the R programming language.
