times-methods: Compute Time Statistics of Sequences

Description

Computes the gaps, the minimum or maximum gap, or the span of sequence.

Usage

## S3 method for class 'timedsequences':
times(x, type = c("times", "gaps", "mingap", "maxgap", "span"))

Arguments

x

an object.

type

a string value specifying the type of statistic.

Value

• 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.
