sequences-class {arulesSequences} | R Documentation |

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`

.

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.

## 3 example sequences x <- list("01" = list(c("A","B"), "C"), "02" = list("C"), "03" = list("B", "B")) ## coerce s <- as(x, "sequences") as(s, "data.frame") ## get reference set as(itemsets(s), "data.frame")
