Hello, I'm new and I'm a beginner. I am learning to use the WGCNA package when I put my data unfortunately after I get this

error: Error in goodGenes (datExpr, weights, goodSamples, goodGenes, minFraction = minFraction,:
datExpr must contain numeric data.


Can not be done with characters? Only numeric?

Thank you very much and have a nice day

the datExpr might have column having character values, probably the gene symbol? could you post head() of the datExp

You need to have expression data for WGCNA analysis.
