brcaMethylData1R Documentation

A matrix with DNA methylation levels from some CpGs on chromosome 1

Description

This object contains methylation levels (0 to 1) for select cytosines in chromosome 1 for TCGA breast cancer patients from a DNA methylation microarray (Illumina 450k microarray). Each row corresponds to one cytosine and the coordinates for these cytosines are in the object brcaMCoord1, (data("brcaMCoord1"), hg38 genome). Only select cytosines on chr1 are included to keep the example data small. Columns are patients, with TCGA patient identifiers as column names. 6004 CpGs and 300 patients are included. DNA methlyation data is Illumina 450k microarray data from breast cancer patients from The Cancer Genome Atlas (TCGA-BRCA, https://portal.gdc.cancer.gov/).
