arulesSequences (version 0.2-1)

inspect-methods: Display Objects

Description

inspect displays a collection of (timed) sequences or sequence rules and their associated quality measures formatted for online inspection.

labels retrieves the string representations of a collection of (timed) sequences or sequence rules.

itemLabels gets the string representations of the set of distinct items or itemsets (elements) associated with a collection of sequences, or sets item labels.

Usage

## S3 method for class 'sequences':
inspect(x, setSep = ",", seqStart = "<", seqend=">" ,="" decode="TRUE)
## S3 method for class 'timedsequences':
inspect(x, setSep = ",", seqStart = "<", seqend=">" ,="" decode="TRUE)
## S3 method for class 'sequencerules':
inspect(x, setSep = ",", seqStart = "<", seqend=">" ,="" rulesep="=>" decode="TRUE)

## S3 method for class 'sequences':
labels(object, setSep = ",", seqStart = "<", seqend=">" ,="" decode="TRUE," ...)<="" p="">
## S3 method for class 'timedsequences':
labels(object, timeStart = "[", timeEnd = "]", setSep = ",",
       seqStart = "<", seqend=">" ,="" decode="TRUE," ...)="" <="" p="">
## S3 method for class 'sequencerules':
labels(object, setSep = ",", seqStart = "<", seqend=">" ,="" rulesep=" => " decode="TRUE," ...)<="" p="">
## S3 method for class 'sequences':
itemLabels(object, itemsets = FALSE, ...)
## S4 method for signature 'sequences, character':
itemLabels(object) <- value

Arguments

x, object

an object.

setSep

a string value specifying the itemset (element) separator.

seqStart

a string value specifying the left sequence delimiter.

seqEnd

a string value specifying the right sequence delimiter.

ruleSep

a string value specifying the separator of the left-hand (antecedent) and the right-hand side (consequent) sequence.

timeStart

a string value specifying the left event time delimiter.

timeEnd

a string value specifying the right event time delimiter.

decode

a logical value specifying if the item indexes should be replaced by item labels.

itemsets

a logical value specifying the type of labels.

...

arguments specifying the markup of itemsets: itemSep = ",", setStart = "{", or setEnd = "}".

value

a character vector of length the number of items of object.

Value

• For method inspect returns x invisibly. For method labels a character vector corresponding with the elements of x.

  For method itemLabels a character vector corresponding with the distinct items or itemsets of object.
