add.edge

delete.edge

Add or delete a directed edge from one or more parents.

Wrappers for functions in the 'gRain' package to emulate some 'RHugin'
functionality, allowing the building of Bayesian networks consisting on discrete
chance nodes incrementally, through   adding nodes, edges and conditional probability
tables, the setting of evidence,   both 'hard' (boolean) or 'soft' (likelihoods),
querying marginal probabilities   and normalizing constants, and generating sets of
high-probability configurations. Computations will typically not be so fast as they are
with 'RHugin', but this package should assist users without access to 'Hugin' to use
code written to use 'RHugin'.

add.edge function

<dl> <dt>domain</dt>
<dd>name of a gRaven domain</dd> <dt>child</dt>
<dd>a character string containing the name of the child node.</dd> <dt>parent</dt>
<dd>a character string specifying by name the parent nodes</dd></dl>

Arguments

Deleting an edge nullifies the CPT for node n, if any.
