R help - Jul 2017 - Error in WGCNA package

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,

First, please read WGCNA FAQ at
https://labs.genetics.ucla.edu/horvath/CoexpressionNetwork/Rpackages/WGCNA/faq.html
regarding using RNA-seq and other count data.

Second, if you insist on using WGCNA on raw count data (which I don't
recommend), use something like

storage.mode(datExpr) = "double"

and try again.
