seqelength: Lengths of event sequences

In TraMineR: Trajectory Miner: a Sequence Analysis Toolkit

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)
