Analyzing TCGA's DNA Methylation data of 301 prostate cancer.

TCGA's DNA Methyaltion data of 301 Prostate Adenocalcinoma patients, based on Illumina's HumanMethylation450 bead chip. A PC with 64GB RAM is not powerful enough to visualize 480k probes x 301 samles. So I'm going to show how to divide data to make it handleable. I hope it gives an idea to whom think they can't work with a big data set on their computers.
