plot.cpStat: Plot method for change point statistics

In robcp: Robust Change-Point Tests

Plot method for change point statistics

Description

Plots the trajectory of the test statistic process together with a red line indicating the critical value (alpha = 0.05) and a blue line indicating the most probable change point location

Usage

## S3 method for class 'cpStat'
plot(x, ylim, xaxt, crit.val, ...)

Arguments

x	object of the class 'cpStat'.
ylim	the y limits of the plot.
xaxt	a character which specifies the x axis type (see par).
crit.val	critical value of the test. Default: 1.358.
...	other graphical parameters (see par).

Details

• Default for ylim is c(min(c(data, 1.358)), max(c(data, 1.358))).

• Default for xaxt is the simliar to the option "s", only that there is a red labelled tick at the most probable change point location. Ticks too close to this will be suppressed.

Value

No return value; called for side effects.
