Description

The CGHresults class is built to store the results of cghseg.

Objects from the Class

Objects can be created by calls of the form new("CGHresults", CGHd, CGHo).

Slots

mu:

list of dataframes containing the position of breakpoints and estimated means (list)

theta:

List of effects used for normalization : waveffect, GCeffect (listOrNULL)

loglik:

Log-likelihood of the selected model (numeric)

nbiter:

number of iterations (numeric)

from:

Name of the function that produced the results (character)

probeID:

Contains the ID of each probe (factor)

genomic.position:

Contains the genomic position of each probe (numeric)

options:

list of options (of class CGHoptions)
