Get states, edges and children in a gRaven domain
Description
Get states, edges and children in a gRaven domain
Usage
get.states(domain, nodes=domain$nodes)
get.children(domain, nodes)
get.edges(domain, nodes=domain$nodes)
Arguments
domain |
name of gRaven domain |
nodes |
name of node(s) |
Details
Emulates functions of the same name in the RHugin package by calls to gRain functions
Value
For get.states, vector of state values. For get.edges,
a list with one element for each node in domain. Each element is in turn a list with a single element edges which is a character vector of names of the node's children.
An empty vector indicates that the node has no children. For get.children,
character vector of children's node names in the case of a single node, otherwise list of children of each node, each element being a character vector of names of the node's children.
Differences from RHugin
get.states and get.children allow more than one node; get.edges allows selecting nodes.
