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, tlim=10, title=NULL,
pbarw=FALSE,
cpal=NULL, missing.color=NA,
ylab, axes="all", xtlab=NULL, cex.plot=1,
withlegend="auto", ltext=NULL, cex.legend=1,
use.layout=(!is.null(group) | withlegend!=FALSE),
legend.prop=NA, rows=NA, cols=NA, ...)
Arguments
seqdata |
a sequence object created with the seqdef function. |
group |
Plots one plot for each level of the factor given as argument. |
tlim |
if tlim>0, shows only the 'tlim' most frequent sequences. Default to 10. |
title |
title for the graphic. Default to NULL. |
pbarw |
if pbarw=TRUE, the width of the bars are proportional to the sequence frequency in the dataset. Default to FALSE. |
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 seqdef ). |
missing.color |
alternative color for representing missing values inside the sequences. By default, this color is taken from the "missing.color" attribute of the sequence object being plotted. |
ylab |
An optional label for the y axis. If set to NA, no label is drawn. |
axes |
if set to "all" (default value) x axes are drawn for each plot in the graphic. If set to "bottom" and group is used, axes are drawn only under the plots located at the bottom of the graphic area. If FALSE, no x axis is drawn. |
xtlab |
optional labels for the x axis ticks labels. If unspecified, the column names of the 'seqdata' sequence object are used (see seqdef ). |
cex.plot |
expansion factor for setting the size of the font for the axis labels and names. The default value is 1. Values lesser than 1 will reduce the size of the font, values greater than 1 will increase the size. |
withlegend |
set wether a legend for the states colors is plotted. The default value 'auto' sets the position of the legend automatically. Other options are 'right'. Obsolete option 'TRUE' is identical to 'auto'. |
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 seqdef ). |
cex.legend |
expansion factor for setting the size of the font for the labels in the legend. The default value is 1. Values lesser than 1 will reduce the size of the font, values greater than 1 will increase the size. |
use.layout |
if TRUE, layout is used to arrange plots when using the group option or plotting a legend. If layout is used, the standard 'par(mfrow=....)' for arranging plots will not work anymore. If withlegend is FALSE and group is NULL, layout is automatically deactivated and 'par(mfrow=....)' will work. |
legend.prop |
sets the proportion of the graphic area used for plotting the legend when use.layout=TRUE and withlegend=TRUE. Default value is set according to the place (bottom or right of the graphic area) where the legend is plotted. Values from 0 to 1. |
rows,cols |
optional arguments to arrange plots when use.layout=TRUE. |
... |
arguments to be passed to the plot function or other graphical parameters. |

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
## 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)
