CGHoptions-class: Class "CGHoptions"

In cghseg: Segmentation Methods for Array CGH Analysis

Description

The CGHoptions class is built to store informations regarding the methods used in the cghseg package

Objects from the Class

Objects can be created by calls of the form new("CGHoptions").

Slots

select:

Model selection to select the number of segments; "mBIC","none" (character)

calling:

calling of segments (logical)

wavenorm:

Wave normalization; "none", "position", "spline" (character)

GCnorm:

GCcontent normalization; "none","linear" (character)

nblevels:

Number of levels when calling (numeric)

alpha:

Proportion of the individual signal length that gives uniKmax.

beta:

Proportion of the sum of uniKmax that gives multiKmax.

itermax:

Maximal number of iterations

nbprocs:

Number of available computer processes

Prototype

CGHo@select = "mBIC"
CGHo@calling = FALSE
CGHo@wavenorm = "position"
CGHo@GCnorm = "none"
CGHo@nblevels = 3
CGHo@alpha = 0.2
CGHo@beta = 0.5
CGHo@itermax = Inf
CGHo@nbprocs = 1
