R Documentation

aCGH Marker Data from Natrajan et al. (2006)

Description

Natrajan et al. (J. Pathology (2006) 210: 49 - 58) used array comparative genomic hybridization to obtain genome-wide DNA copy number data from 97 Wilms' tumor samples at 3288 markers. This data frame contains the marker information for the arrays. Each row corresponds to a marker, and column 1 lists the chromosome number, column 2 is the marker position (in base pairs), and column 3 is the marker name.

Usage

data(wilms.markers)

Format

A data frame with 3288 observations on the following 3 variables.

Chromosome

The chromosome for the given marker

Position

The position (in bp) for the given marker

Name

The name of the marker (e.g. R:A-MEXP-192:RP11-465B22)
