vpaL2adjMAT

vpaL2tfM

A list of generators for an undirected graph.

glist

A list of the form (v,pa(v)) specifying a directed acyclic graph.

vpaL

The names of the vertices in the graphs. These will be the row and
    column names of the matrix

Either <code>"matrix"</code> or <code>"Matrix"</code> (for a sparse
    matrix representation)

result

Creates adjacency matrix for a graph from a list of generators. The
  graph is assumed to be undirected.

utilities

The gRbase package provides certain general constructs
        which are used by other graphical modelling packages, in
        particular by the packages gRain, gRim and gRc.

 gRbase contains several datasets relevant for use in connection with
        graphical models. Almost all datasets used in the book
        Graphical Models with R (2012) are contained in gRbase.

 gRbase implements several graph algorithms (based mainly on
        representing graphs as adjacency matrices - either in the form
        of a standard matrix or a sparse matrix). Some graph algorithms
        are: * maximum cardinality search (for marked and unmarked
        graphs).  * moralize * triangulate * junctionTree

 gRbase facilities for array operations,

 gRbase implements functions for testing for conditional independence.

 gRbase illustrates how hierarchical log-linear models (hllm) may be
        implemented and describes concept of gmData (graphical meta
        data). These features, however, are not maintained anymore and
        remains in gRbase only because there exists a paper describing
        these facilities: A Common Platform for Graphical Models in R:
        The gRbase Package, Journal of Statistical Software, Vol 14, No
        17, 2005.
