Plot method for the class 'aCGHsegmented'
Description
Plots fitted piecewise constant lines.
Usage
## S3 method for class 'aCGHsegmented'
plot(x, add = FALSE, y = TRUE, psi.lines = TRUE, typeL="l",
what=c("lines","criterion"), ...)
Arguments
x |
object of class "aCGHsegmented" returned by jumpoints .
|
add |
logical; if TRUE the fitted piecewise constant lines are added
to an existing plot.
|
y |
logical; if TRUE the observations are also plotted, otherwise only the fitted lines.
|
psi.lines |
logical; if TRUE vertical lines corresponding to the estimated changepoints are added.
|
typeL |
argument type for the fitted lines. Possible options are typeL="s" to plot the horizontal and vertical lines of the step-function, and
typeL="l" to draw the horizontal lines only.
|
what |
If 'lines' the fitted lines are plotted, otherwise the criterion values versus the number of change points, provided the fitted object x has been
called with argument output='2' or output='3' .
|
... |
possible additional graphical arguments, such as col , xlab , and so on.
|
Details
This fuction takes a fitted object returned by jumpoints
and plots
the resulting fit, namely the estimated step-function and changepoints.
Value
The function simply plots the fit returned by 'jumpoints'.
