fm.is_inset_sparse | R Documentation |
Checks if element i (1-based) belongs to the tuple indexed A (whose cardinality can be 1,2, other (automatically determined)).
fm.is_inset_sparse(A, card, i, envsp=NULL)
A |
Tuple indexed. |
card |
Whose cardinality can be 1,2, other (automatically determined) |
i |
Element (1-based) |
envsp |
Structure required for sparse representation which stores the relevant values (k-tuples). It is obtained from fm.PrepareSparseFM(n). |
output |
The output is a logical value. |
