cpt.geo-class: Class '"cpt.geo"'

In changepoint.geo: Geometrically Inspired Multivariate Changepoint Detection

Class "cpt.geo"

Description

A class for cpt.geo objects.

Objects from the Class

Objects can be created by calls of the form new("cpt.geo", ...).

new('cpt.geo',...):

Creates a new object with class cpt.geo

Slots

data.set:

Object of class "matrix", original data set to be analyzed for changepoints

distance:

Object of class "numeric", distance mapping of each time vector.

angle:

Object of class "numeric", angle mapping of each time vector.

penalty:

Object of class "character", type of penalty used as a text string.

pen.value:

Object of class "numeric", numeric value of penalty used.

test.stat:

Object of class "character", test statistic used for the analysis.

msl:

Object of class "numeric", minimum segment length (no. of observations between changepoints).

nquantiles:

Object of class "numeric", number of quantiles used in the empirical distribution.

dist.cpts:

Object of class "numeric", changepoint locations in the distances.

ang.cpts:

Object of class "numeric", changepoint locations in the angles.

date:

Object of class "character", date the analysis was run.

version:

Object of class "character", version number of the package when analysis was run.

Examples

showClass("cpt.geo")	#shows the structure of the cpt.geo class.

x=new('cpt.geo')	#creates a new object with the cpt.geo class defaults
dist.cpts(x)		#retrieves the dist.cpts slot from x
dist.cpts(x) <- c(50,100) #replaces the dist.cpts slot from x with c(50,100)
