Dear all , I would like to reconstruct coexpression networks from proteomic count data having integer values. Some internal function doesn't like to work well with integers. How can this error be rectified? > adjacency = adjacency(datExpr, power = softPower, type = "signed"); Error in cor(datExpr, use = "p") : REAL() can only be applied to a 'numeric', not a 'integer' Appreciate your help , Many thanks Best Regards, Ankush Sharma [[alternative HTML version deleted]]

Hi, I'm running a tutorial ("Meta-analyses of data from two (or more) microarray data sets"), which use wgcna package. I have an error in the function modulePreservation (it is below). I'm using R2.13 Can you help me? Do you know, what is happens? Thanks Raquel multiExpr = list(A = list(data=t(badea)),B = list(data=t(mayo))) # two independent datasets (dim = 13447 x 36) mp =
