seqfplot: 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, tlim=10, title=NULL, cpal=NULL, pbarw=FALSE,
	withlegend=TRUE, ltext=NULL, xtlab=NULL, bmar=1)

Arguments

seqdata

a sequence object created with the seqdef function.

tlim

if tlim>0, shows only the 'tlim' most frequent sequences. Default to 10.

title

title for the graphic. Default to NULL.

cpal

alternative color palette to use for the states. If user specified, a vector of colors with number of elements equal to the number of distinct states. By default, the 'cpal' attribute of the 'seqdata' sequence object is used (see

pbarw

if pbarw=TRUE, the width of the bars are proportional to the sequence frequency in the dataset. Default to FALSE.

withlegend

if TRUE, a legend is plotted. Default to TRUE.

ltext

optional description of the states to appear in the legend. Must be a vector of character strings with number of elements equal to the number of distinct states. If unspecified, the 'label' attributes of the 'seqdata' sequence object is used (see

xtlab

optional labels for the x axis ticks labels. If unspecified, the column names of the 'seqdata' sequence object are used (see seqdef).

bmar

base margin for the top and bottom of the graphic, that is, the amount of white space surrouding it.

Examples

## Plot of the 10 most frequent sequences 
## with equal bar width
data(biofam)

biofam.seq <- seqdef(biofam,10:25) 
seqfplot(biofam.seq)

## The same plot with
## proportional bar width
seqfplot(biofam.seq, pbarw=TRUE)
