getMinorMajorCopyNumbers: Get minor and major copy number labels from region annotation labels

Description

Get minor and major copy number labels from region annotation labels

Usage

getMinorMajorCopyNumbers(region)

Arguments

region

A character value, the annotation label for a copy number region. Should be encoded as "(C1,C2)", where

C1

denotes the minor copy number, that is, the smallest of the two parent-specific copy numbers

C2

denotes the minor copy number, that is, the smallest of the two parent-specific copy numbers

Value

A matrix with length(region) rows and two columns: C1 and C2, as described above.
