times-methods {arulesSequences} | R Documentation |
Computes the gaps, the minimum or maximum gap, or the span of sequences.
## S4 method for signature 'timedsequences' times(x, type = c("times", "gaps", "mingap", "maxgap", "span"))
x |
an object. |
type |
a string value specifying the type of statistic. |
If type = "items"
returns a list of vectors of events times
corresponding with the elements of a sequence.
If type = "gaps"
returns a list of vectors of time differences
between consecutive elements of a sequence.
Otherwise, a vector corresponding with the elements of x
.
Gap statistics are not defined for sequences of size one, i.e. which
contain a single element. NA
is used for undefined values.
FIXME lists are silently reduced to vector if possible.
