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 = modulePreservation(multiExpr,multiColor,referenceNetworks=1,verbose=3,networkType="signed",nPermutations=2,maxGoldModuleSize=100,maxModuleSize=400)
