Description Objects from the Class Slots Extends Methods Note Author(s) See Also Examples

Represents a collection of sequences and the associated quality measures.

Most frequently, objects are created by a sequence mining algorithm such as cSPADE as the return value.

Objects can also be created by calls of the form
`new("sequences", ...)`

.

`elements`

:an object of class

`itemsets`

containing a sparse representation of the unique elements of a sequence.`data`

:an object of class

`sgCMatrix`

containing a sparse representation of ordered*lists*(collections of) indexes into the unique elements.`sequenceInfo`

:a data frame which may contain additional information on a sequence.

`quality`

:a data.frame containing the quality measures of a sequence.

`tidLists`

:an object of class

`tidLists`

mapping supporting sequences, or`NULL`

.

`is.closed`

`signature(x = "sequences")`

; returns a logical vector indicating if a sequence has no proper superset in`x`

which has the same support.`is.maximal`

`signature(x = "sequences")`

; returns a logical vector indicating if a sequence is not a subsequence of any other sequence in`x`

.`is.subset`

`signature(x = "sequences")`

`is.superset`

`signature(x = "sequences")`

`itemFrequency`

`signature(x = "sequences")`

Coercion from an object of class
`transactions`

with
temporal information to an object of class `sequences`

is not provided as this information would be lost. Use class
`timedsequences`

instead.

Currently, a general method for concatenation of sequences similar
to `cbind`

, is not provided.
