I am trying to run WGCNA analysis on a microarray dataset. I have been following this tutorial: https://bioinformaticsworkbook.org/tutorials/wgcna.html#gsc.tab=0 I am confused about the subheading "Relate Module (cluster) Assignments to Treatment Groups." The question is: Can we see how each module is associated with the treatment group as a measure of correlation? My question arises since the name of a 'treatment group' essentially is not a numeric value that can be used to calculate the correlation. From what I understand in the tutorial, the name 'corr' and values (-1,1) are the input given in the code, not the actual correlation function used. please let me know if I am understanding this correctly (or not).
Also requesting to share some resources if there are any on the same. Thanks in advance!
