seqdur: Extract state durations from a sequence object.

Description

Extracts states durations from a sequence object. Returns a matrix containing the states durations for the sequences. The states durations in 'D-D-D-D-A-A-A-A-A-A-A-D' are 4,7,1. Distinct states can be extracted with the seqdss function.

Usage

seqdur(seqdata, with.missing=FALSE)

Arguments

seqdata

a sequence object as defined by the seqdef function.

with.missing

if set to TRUE, durations are also computed for missing statuses (gaps in sequences). See seqdef on options for handling missing values when creating sequence objects.

Value

• a matrix containing the states durations for each distinct state in each sequence.

seqdss.

Examples

## Creating a sequence object with the columns 13 to 24
## in the 'actcal' example data set
data(actcal)
actcal.seq <- seqdef(actcal,13:24)

## Retrieving the DSS
actcal.dur <- seqdur(actcal.seq)

## Displaying the durations for the first 10 sequences
actcal.dur[1:10,]
