WGCNA Data Cleaning

Question

[mruy3]

Hi!

I'm new here in bioinformatics. I'm currently using WGCNA for my data analysis of my RNA-Seq data. I'm following the UCLA tutorial and the codes they use for R. However, I encountered this problem and cannot proceed further:

gsg = goodSamplesGenes(datExpr0, verbose = 3);
Error in goodSamplesGenes(datExpr0, verbose = 3) : 
  could not find function "goodSamplesGenes"

How should I go about this?

Thank you so much for your help.

Can you confirm that the package installed and loaded successfully?

What is the output of library(WGCNA) or require(WGCNA)?
