The sparta package implements new methods (multiplication,
marginalization etc.) for dealing with conditional probability tables
(CPTs) and are especially useful when the CPTs are sparse.

The jti, https://github.com/mlindsk/jti, package (on CRAN)
implements belief propagation via the Junction Tree Algorithm which
relies heavily on sparta tables. See also
https://github.com/mlindsk/pednoa for a usecase of jti where
“ordinary/dense” table operations will fail.
