State frequencies in the whole sequence data set

Share:

Description

Overall frequency of each state of the alphabet in the state sequence object.

Usage

1
seqstatf(seqdata, weighted = TRUE)

Arguments

seqdata

a sequence object as defined by the seqdef function.

weighted

Logical. Should frequencies account for weights when present in the state sequence object (see seqdef). Default is TRUE. If no weights were assigned during the creation of the sequence object, weighted=TRUE will yield the same result as weighted=FALSE since each sequence is allowed a weight of 1.

Details

The seqstatf function computes the (weighted) count and frequency of each state of the alphabet in seqdata, i.e., the (weighted) sum of the occurrences of a state in seqdata.

Value

A data frame with as many rows as states in the alphabet and two columns, one for the count (Freq) and one for the percentage frequencies (Percent).

## Creating a sequence object from the actcal data set
data(actcal)
actcal.lab <- c("> 37 hours", "19-36 hours", "1-18 hours", "no work")
actcal.seq <- seqdef(actcal, 13:24, labels=actcal.lab)

## States frequencies
seqstatf(actcal.seq)

## Example with weights
data(ex1)
ex1.seq <- seqdef(ex1, 1:13, weights=ex1$weights)

## Unweighted
seqstatf(ex1.seq, weighted=FALSE)

## Weighted
seqstatf(ex1.seq, weighted=TRUE)
