I am using topGo following this outline https://datacatz.wordpress.com/2018/01/19/gene-set-enrichment-analysis-with-topgo-part-1/

At the end of my analysis, I visualize the result with showSigOfNodes:

showSigOfNodes(GOdata, score(weight_fisher_result), useInfo = "all", sigForAll=FALSE, firstSigNodes=2,.NO.CHAR=50)

This gives me GO-IDs in each node like this, GO:0008150, which is not very useful to me, I want human-readable text instead. I figured out that another valid value for useInfo is "all", which gives me node labels like this:

GO:0008150
biological_process
1.000000
162 / 13984

• How can I make it so that the node label is the human-readable description only? I.e. in the example the string "biological_process" only should appear as the node label?
• What are the valid values for useInfo and how am I supposed to find out what they are? In the showSigOfNodes documentation I only find useInfo: aditional info to be ploted to each node.
