unity tables now have a rank attribute which is just the unique value that all cells have. Because of this, a unity table can now be multiplied with a scalar. And regular sparta tables can be multiplied with unities of different rank. As a consequence, unities can now be marginalized also.
New function equiv
to test if two sparta objects are identical
Fixed a bug when assigning dimnames to the result of multiplication
marg
, slice
, mult
and div
has been fixed. These functions were prone to errors when the number of variables exceed 10
.
