Description
Correlation Heatmaps.
Description
Create correlation heatmaps from a numeric matrix. Ensembl Gene ID row names can be converted to Gene Symbols using, e.g., BioMart. Optionally, data can be clustered and filtered by correlation, tree cutting and/or number of missing values. Genes of interest can be highlighted in the plot and correlation significance be indicated by asterisks encoding corresponding P-Values. Plot dimensions and label measures are adjusted automatically by default. The plot features rely on the heatmap.n2() function in the 'heatmapFlex' package.

Example dataset
Example datasets can be found at coreheat/inst/extdata or can be obtained from the example data directory at github. A dataset consisting of 333 patients with primary prostate cancer was downloaded from The Cancer Genome Atlas (TCGA) via the cBioPortal for Cancer Genomics and two subsets were created, PrCaTCGASample.txt containing genes commonly associated with cancer, and PrCaTCGASample_5000.txt containing 500 genes selected at random.
