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.
