ClusterProbes: The ClusterProbes function

Description Usage Arguments Value

Description

This function uses the annotation for Illumina methylation arrays to map each probe to a gene. Then, for each gene, it clusters all its CpG sites using hierchical clustering and Pearson correlation as distance and complete linkage. If data for normal samples is provided, only overlapping probes between cancer and normal samples are used. Probes with SNPs are removed. This function is prepared to run in parallel if the user registers a parallel structure, otherwise it runs sequentially. This function also cleans up the sample names, converting them to the 12 digit format.

Usage

1
ClusterProbes(MET_Cancer, MET_Normal, CorThreshold = 0.4)

Arguments

MET_Cancer

data matrix for cancer samples.

MET_Normal

data matrix for normal samples.

CorThreshold

correlation threshold for cutting the clusters.

Value

List with the clustered data sets and the mapping between probes and genes.
