bigcor: Large correlation matrices in R

http://rmazing.wordpress.com/2013/02/22/bigcor-large-correlation-matrices-in-r/


It has been shown that by calculating the Pearson correlation between genes, one can identify (by high \varrho values, i.e. > 0.9) genes that share a common regulation mechanism such as being induced/repressed by the same transcription factors:
I had an idea. How about using my microarray data of gene expression of 40000 genes in 28 samples and calculate the correlation between all 40000 genes (variables).
