plot.seqdiff: Plotting a seqdiff object.

In TraMineR: Trajectory Miner: a Sequence Analysis Toolkit

Plotting a seqdiff object.

Description

Plot method for the sliding values returned by seqdiff. Plots a statistic (the Pseudo R2 by default) along the position axis.

Usage

## S3 method for class 'seqdiff'
plot(x, stat = "Pseudo R2", type = "l", ylab = stat,
  xlab = "", legend.pos = "top", ylim = NULL, xaxis = TRUE, col = NULL,
  xtstep = NULL, tick.last = NULL, legendposition, xaxt, ...)

Arguments

x	an object produced by seqdiff
stat	character. Name of the statistic to be plotted. Can be any of the statistics returned by seqdiff or "discrepancy". See details.
type	the line type, see lines
ylab	character: y-axis label.
xlab	character: x-axis label.
legend.pos	character: position of the line legend, see legend
ylim	numeric: if not NULL, range of the y-axis.
xaxis	logical: if TRUE an x-axis is plotted.
col	list of colors to use for each line.
xtstep	integer: optional step between tick-marks and labels on the x-axis. If unspecified, the xtstep attribute of the sequence object x is used. (see seqdef)
tick.last	Logical. Should a tick mark be enforced at the last position on the x-axis? If unspecified, the tick.last attribute of the x object is used.
legendposition	Deprecated. Use legend.pos instead.
xaxt	Deprecated. Use xaxis instead.
...	Additional parameters passed to lines

Details

The function plots the sliding values of the requested statistic.

You can plot the evolution of two statistics by providing for instance stat=c("Pseudo R2", "Levene").

Use stat="discrepancy" to plot the within-discrepancies.

For "discrepancy", a separate line is drawn for the whole set of sequences and for each group. Those two values cannot be paired with another statistic.
