if input blocks was given, its copy; otherwise a vector of length equal number<br />
of genes giving the block label for each gene. Note that block labels are not<br />
necessarilly sorted in the order in which the blocks were processed (since we do<br />
not require this for the input blocks). See blockOrder below.<br />
a vector giving the order in which blocks were processed and in which blockGenes<br />
above is returned. For example, blockOrder[1] contains the label of the<br />
first-processed block.<br />
logical indicating whether the module eigengenes were calculated without errors.<br />
Note<br />
If the input dataset has a large number of genes, consider carefully the maxBlockSize as it significantly<br />
affects the memory footprint (and whether the function will fail with a memory allocation<br />
error). From a theoretical point of view it is advantageous to use blocks as large as possible; on the<br />
other hand, using smaller blocks is substantially faster and often the only way to work with large<br />
numbers of genes. As a rough guide, it is unlikely a standard desktop computer with 4GB memory<br />
or less will be able to work with blocks larger than 8000 genes.<br />
