seqdss: Extract distinct states sequence from a sequence object

Description

Extract distinct states sequence from a sequence object. Returns a sequence object containing the distinct states sequences, ie the durations are not taken into account. The DSS contained in 'D-D-D-D-A-A-A-A-A-A-A-D' is 'D-A-D'. Durations can be extracted with the 'seqdur' function.

Usage

seqdss(seqdata)

Arguments

seqdata

a sequence object as defined by the seqdef function.

Value

• a sequence object containing the distinct state sequence (DSS) for each sequence in the object given as argument.

See Also

seqdur.

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.dss <- seqdss(actcal.seq)
  
## Displaying the DSS for the first 10 sequences
actcal.dss[1:10,]
