plot.stslist.freq {TraMineR} | R Documentation |
Plot method for output produced by the seqmeant function, i.e objects of class stslist.freq.
## S3 method for class 'stslist.freq': plot(x, cpal = NULL, missing.color = NULL, pbarw = TRUE, ylab = NULL, yaxis = TRUE, xaxis = TRUE, xtlab = NULL, cex.plot = 1, ...)
x |
an object of class stslist.freq as produced by the seqtab function. |
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 states in the alphabet. By default, the 'cpal' attribute of the x object is used. |
missing.color |
alternative color for representing missing values inside the sequences. By default, this color is taken from the missing.color attribute of the object being plotted. |
pbarw |
if pbarw=TRUE (default), the width of the bars are proportional to the sequence frequency in the dataset. |
ylab |
an optional label for the y axis. If set to NA, no label is drawn. |
yaxis |
if TRUE or "cum", the y axis is plotted with a label showing the cumulated percentage frequency of the displayed sequences. If "pct", the percentage value for each sequence is displayed. |
xaxis |
if TRUE (default) the xaxis is plotted. |
xtlab |
optional labels for the x axis ticks. If unspecified, the names attribute of the x object is used. |
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. |
... |
further graphical parameters. For example border=NA to remove the bars borders, space=0 to remove space between sequences. For more details about the graphical parameter arguments, see barplot and par . |
This is the plot method for the output produced by the seqtab
function, i.e. objects of class stslist.freq. It produces a plot showing the sequences sorted bottom up according to their frequency in the data set.
This method is called by the generic seqplot
function (if type="f"
) that produces more sophisticated plots, allowing grouping and automatic display of the states legend. The seqfplot
function is a shortcut for calling seqplot
with type="f"
.
