cghSeg2order: Genomic ordering of cghSeg-objects.

In sigaR: Statistics for Integrative Genomics Analyses in R

Description

Orders the features within a cghSeg-object in accordance with their genomic order.

Usage

cghSeg2order(CNdata, chr, bpstart, verbose=TRUE)

Arguments

CNdata	Object of class cghSeg.
chr	Column in the slot featureData of the cghSeg-object specifying the chromosome information of the features.
bpstart	Column in the slot featureData of the cghSeg-object specifying the start basepair information of the features.
verbose	Logical indicator: should intermediate output be printed on the screen?

Value

Object of class cghSeg, now genomically ordered.
