Plot method for objects produced by the seqstatd function
This is the plot method for output produced by the seqstatd function, i.e for objects of class stslist.statd.
## S3 method for class 'stslist.statd' plot(x, type = "d", cpal = NULL, ylab = NULL, yaxis = TRUE, xaxis = TRUE, xtlab = NULL, xtstep = NULL, tick.last = NULL, cex.axis = 1, space = 0, xlab = NULL, cex.plot, ...)

cpal |
alternative color palette to be used 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 |

optional labels for the ticks of the x-axis. If unspecified, the |
xtstep |
optional interval at which the tick-marks and labels of the x-axis are displayed. For example, with xtstep=3 a tick-mark is drawn at position 1, 4, 7, etc... The display of the corresponding labels depends on the available space and is dealt with automatically. If unspecified, the |

This is the plot method for the output produced by the seqstatd function, i.e. for objects of class stslist.statd. If type="d" it produces a state distribution plot presenting the sequence of the transversal state frequencies at each successive (time) position, as computed by the seqstatd function. With type="Ht", the series of entropies of the transversal state distributions is plotted.
This method is called by the generic seqplot function (if type="d" or type="Ht") that produces more sophisticated plots, allowing grouping and automatic display of the state color legend. The seqdplot and seqHtplot functions are shortcuts for calling seqplot with type="d" or type="Ht" respectively.
The plotted values, i.e. for type="d" the cross-sectional distributions, and for type="Ht" the cross-sectional entropies.
## 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)
## State distribution
biofam.statd <- seqstatd(biofam.seq)
## State distribution plot (default type="d" option)
plot(biofam.statd)
## Entropy index plot
plot(biofam.statd, type="Ht")Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
