seqeweight: Setting or retrieving weights of an event sequence object.

In TraMineR: Trajectory Miner: a Sequence Analysis Toolkit

Setting or retrieving weights of an event sequence object.

Description

Event sequence objects can be weighted. Weights are used by other functions such as seqefsub or seqecmpgroup to compute weighted statistics.

Usage

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

Arguments

eseq	An event sequence object (seqelist).
value	Numerical vector containing weights
s	Deprecated. Use eseq instead.

Value

seqeweight returns a numerical vector containing the weights associated to each event sequence.

Examples

##Starting with states sequences
##Loading data
data(biofam)
## Creating state sequences
biofam.seq <- seqdef(biofam,10:25,informat='STS')

## Creating event sequences from biofam
biofam.eseq <- seqecreate(biofam.seq, weighted=FALSE)

## Using the weights
seqeweight(biofam.eseq) <- biofam$wp00tbgs

## Now seqefsub accounts for weights unless weighted is set to FALSE
fsubseq <- seqefsub(biofam.eseq, pmin.support=0.01)

## Searching for weighted susbsequences which best
## discriminate the birth cohort
discr <- seqecmpgroup(fsubseq, group=biofam$birthyr>=1940)
plot(discr[1:15])
