seqfplot {TraMineR}R Documentation

Graphic presenting the frequency of sequences

Description

The sequences are presented as stacks of successive states, ordered by their relative frequency in the dataset.

Usage

 seqfplot(seqdata, group=NULL, title=NULL, tlim=NULL, pbarw=FALSE, ...)

Arguments

seqdata a sequence object created with the seqdef function.
group Plots one plot for each level of the factor given as argument.
title title for the graphic. Default to NULL.
tlim if tlim>0, shows only the 'tlim' most frequent sequences. If tlim=NULL (default), the 10 most frequent sequences are displayed.
pbarw if pbarw=TRUE, the width of the bars are proportional to the sequence frequency in the dataset. Default to FALSE.
... arguments to be passed to the plot.stslist function or other graphical parameters. Use axes for controling the display of axes, withlegend for controling the display of a legend for the plot, etc...

plot.stslist, seqtab.

Examples

## Defining a sequence object with the data in columns 10 to 25
## (family status from age 15 to 30) in the biofam data set
data(biofam)
biofam.lab <- c("Parent", "Left", "Married", "Left+Marr",
"Child", "Left+Child", "Left+Marr+Child", "Divorced")
biofam.seq <- seqdef(biofam, 10:25, labels=biofam.lab)

## Plot of the 10 most frequent sequences 
## with equal bar width
seqfplot(biofam.seq)

## The same plot with
## proportional bar width
## grouped by sex
seqfplot(biofam.seq, group=biofam$sex, pbarw=TRUE)

## The same plot without legend,
## axes and labels
seqfplot(biofam.seq, group=biofam$sex, pbarw=TRUE, 
        axes=FALSE, ylab=NA, withlegend=FALSE)
