The 'gRbase' package provides graphical modelling features
used by e.g. the packages 'gRain', 'gRim' and 'gRc'. 'gRbase' implements
graph algorithms including (i) maximum cardinality search (for marked
and unmarked graphs).
(ii) moralization, (iii) triangulation, (iv) creation of junction tree.
'gRbase' facilitates array operations,
'gRbase' implements functions for testing for conditional independence.
'gRbase' illustrates how hierarchical log-linear models may be
implemented and describes concept of graphical meta
The facilities of the package are documented in the book by Højsgaard,
