Get belief in a gRaven domain

Description

Find the configurations of the specified nodes that occur with probability pmin or greater. These configurations are known as most probable configurations or maximum a posteriori (MAP) configurations.

Usage

map.configurations(domain, nodes, pmin)

Arguments

`domain`	name of gRaven domain
`nodes`	character vector of names of nodes
`pmin`	a single numeric value between 0 and 1 specifying the minimum probability for the most probable configurations

Details

Emulates function of the same name in the RHugin package by calls to gRain functions

Value

Data.frame with one column for each node in nodes. Each row contains a most probable configuration. The final column of the data.frame (Prob) gives the probability of the configuration.
