fm.tuple_cardinality_sparse {Rfmtool}

Tuple cardinality

Description

Returns the cardinality of the tuple numbered i in the list of tuples.

Usage

  fm.tuple_cardinality_sparse(i, envsp = NULL)

Arguments

i

In the list of tuples.

envsp

Structure required for sparse representation which stores the relevant values (k-tuples). It is obtained from fm.PrepareSparseFM(n).

Value

output

The output is the cardinality of the tuple numbered i in the list of tuple.
