Description Usage Arguments Details Value Author(s) See Also Examples
Induce a set of strong sequence rules from a set of frequent sequences, i.e. which (1) satisfy the minimum confidence threshold and (2) which contain the last element of the generating sequence as the righthand side (consequent) sequence.

ruleInduction(x, transactions, confidence = 0.8, control = NULL)

x 
an object. 
transactions 
an optional object of class

confidence 
a numeric value specifying the minimum confidence threshold. 
control 
a named list with logical component 
If transactions
is not specified, the collection of sequences
supplied must be closed with respect to the rules to be induced. That
is, the left and the righthand side sequence of each candidate rule
must be contained in the collection of sequences. However, using timing
constraints in the mining step the set of frequent sequences may not be
closed under rule induction.
Otherwise, x
is completed (augmented) to be closed under rule
induction and the support is computed from transactions
, using
method ptree. Note that, rules for added sequences, if any, are not
induced.
