seqiplot: Visualization of individual sequences.

Description

Plots a graphic showing individual sequences as stacked bars.

Usage

seqiplot(seqdata, tlim=1:10, sortv=NULL, statl=NULL, 
   title=NULL, cpal=NULL, 
   withlegend=TRUE, withborder=TRUE, space=NULL, 
   ltext=NULL, slab=FALSE, xtlab=NULL, bmar=1)

Arguments

seqdata

a sequence object created with the seqdef function.

tlim

interval representing the range to be plotted. Default to 1:10, ie the first 10 rows. Set to 0 if you want to plot all sequences in 'seqdata'.

sortv

name of an optional variable used to sort the data before plotting

statl

list of states for the plot. Usefull for several plots to have the same colors representing the same states. If not specified, the state list for the plot is taken from seqdata.

withlegend

if TRUE, a legend is added to the plot. Default to FALSE.

title

title for the graphic. Default to NULL.

cpal

alternative collor palette for the states. Must be a vector of color names with number of elements equal to the number of states in seqdata. By default, colors are obtained with the RColorBrewer package (accent palette).

withborder

if TRUE, plots the borders of the bars cells. Default to TRUE.

space

sets the space between each sequence in the plot. Setting to 0 yiels no space and is usefull if plotting a large amount of sequences. Default to NULL, ie space value is automaticaly computed.

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

slab

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

data(actcal)
 
## Plotting the first 10 sequences in the 'actcal' example data set
seqiplot(seqdef(actcal,13:24))

## Plotting the all the sequences in the 'biofam' example data set
## using 'withborder=FALSE' and 'space=0' options to have a nicier
## plot
data(biofam)
seqiplot(seqdef(biofam,10:25),tlim=0,withborder=FALSE,space=0)
