Calculate approximate hub gene significance for all modules in network.
hubGeneSignificance(datKME, GS)a data frame (or a matrix-like object) containing eigengene-based connectivities of all genes in the network.
a vector with one entry for every gene containing its gene significance.
A vector whose entries are the hub gene significances for each module.
In datKME rows correspond to genes and columns to modules.
