R: Lengths of event sequences

seqelength {TraMineR} | R Documentation

## Lengths of event sequences

### Description

The length of an event sequence is its time span, i.e., the total time of observation. This information is useful to perform for instance a survival analysis. The function `seqelength` retrieves the lengths of the provided sequences, while `seqelength <-` sets the length of the sequences.

### Usage

    seqelength(eseq, s)
    seqelength(eseq, s) <- value

### Arguments

`eseq` | An event sequence object (`seqelist`).
`value` | A list of sequence lengths.
`s` | Deprecated. Use `eseq` instead.

### Value

A numeric vector with the lengths of the sequences.

### Examples

    data(actcal.tse)
    actcal.eseq <- seqecreate(actcal.tse)
    ## Since end.event is not specified, contains no sequence lengths
    ## We set them manually as 12 for all sequences
    sl <- numeric()
    sl[1:2000] <- 12
    seqelength(actcal.eseq) <- sl
    actcal.eseq[1:10]
    ## Retrieve lengths
    slen <- seqelength(actcal.eseq)
    summary(slen)
