| plot.stslist.modst {TraMineR} | R Documentation |
Plot method for output produced by the seqmodst function, i.e objects of class stslist.modst.
## S3 method for class 'stslist.modst': plot(x, cpal = NULL, ylab = NULL, yaxis = TRUE, xaxis = TRUE, xtlab = NULL, cex.plot = 1, ...)
x |
an object of class stslist.modst as produced by the seqmodst 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. |
ylab |
an optional label for the y axis. If set to NA, no label is drawn. |
yaxis |
if TRUE (default) the y axis is plotted. |
xaxis |
if TRUE (default) the x axis 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 more details about the graphical parameter arguments, see barplot and par. |
This is the plot method for the output produced by the seqmodst function, i.e. objects of class stslist.modst. It produces a plot showing the sequence of modal states with bar width proportional to the state frequencies.
This method is called by the generic seqplot function (if type="ms") that produces more sophisticated plots, allowing grouping and automatic display of the states legend. The seqmsplot function is a shortcut for calling seqplot with type="ms".
## 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)
## Modal state sequence
biofam.modst <- seqmodst(biofam.seq)
plot(biofam.modst)
