seqedplot: Graphical representation of a set of events sequences.

In TraMineRextras: TraMineR Extension

Graphical representation of a set of events sequences.

Description

This function provides two ways to represent a set of events. The first one (type="survival") plots the survival curves of the first occurrence of each event. The second one (type="hazard") plots the mean counts of each event in the successive periods.

Usage

seqedplot(seqe,
    group=NULL, breaks=20, ages=NULL,
    main="auto", type="survival", ignore=NULL,
	with.legend="auto",cex.legend=1,
    use.layout=(!is.null(group) | with.legend!=FALSE), legend.prop=NA,
    rows=NA, cols=NA,
    xaxis="all", xlab="time",
    yaxis="all",
    ylab=ifelse(type=="survival", "survival probability", "mean number of events"),
    cpal=NULL,
    title, withlegend, axes, ...)

Arguments

seqe	an event sequence object as defined by the seqecreate function.
group	Plots one plot for each level of the factor given as argument.
breaks	Number of breaks defining a period.
ages	Two numeric values representing minimum and maximum ages to be represented.
main	String. Title of the graphic. Default is "auto", i.e., group levels. Set as NULL to suppress titles.
type	String. Type of One of "survival" or "hazard". If type="survival", survival curves of the first occurrence of each event are plotted. If type="hazard", mean numbers of each event in the successive periods are plotted.
ignore	Character vector. An optional list of events that should not be plotted.
with.legend	Logical or string. Defines if and where the legend of the state colors is plotted. The default value "auto" sets the position of the legend automatically. Other possible values are "right" or FALSE. Obsolete value TRUE is equivalent to "auto".
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. When layout is activated, the standard par(mfrow=....) for arranging plots does not work. With with.legend=FALSE and group=NULL, layout is automatically deactivated and par(mfrow=....) can be used.
legend.prop	proportion of the graphic area used for plotting the legend when use.layout=TRUE and with.legend=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	optional arguments to arrange plots when use.layout=TRUE.
cols	optional arguments to arrange plots when use.layout=TRUE.
xaxis	Logical or one of "all" and "bottom". If set as TRUE or "all" (default value) x-axes are drawn on each plot in the graphic. If set as "bottom" and group is used, x-axes are drawn under the plots of the bottom panel only. If FALSE, no x-axis is drawn.
yaxis	Logical or one of "all" or "left". If set as TRUE or "all" (default value) y-axes are drawn on each plot in the graphic. If "left" and group is used, the y-axis is displayed on plots of the left panel only. If FALSE no y-axis is drawn.
xlab	an optional label for the x-axis. If set to NA, no label is drawn.
ylab	an optional label for the y-axis. If set to NA, no label is drawn. Can be a vector of labels by group level.
cpal	Color palette used for the events. If NULL, a new color palette is generated.
title	Deprecated. Use main instead.
withlegend	Deprecated. Use with.legend instead.
axes	Deprecated. Use xaxis instead.
...	Additional arguments passed to plot.survfit, lines.survfit, and/or legend.
