[astridsph-sudo]

I hope one R genius can help me crack my code problem.

I am performing GSEA form a DeSeq2 analysed object, the past code has worked before with the given dataset, but somehow the KEGG analysis is currently not working for me (Error pasted below). Alongside I am also running GO and Reactome using:

gseGO() and gsePathway ()

Both are working

I work from a server if this is important

library(clusterProfiler)
> library(org.Hs.eg.db)
> 
> res_id <- res_id[!duplicated(res_id[c("entrezgene_id")]),]
> res_gsea<- as.vector(res_id$log2FoldChange)
> names(res_gsea)<-res_id$entrezgene_id
> 
> 
> KEGGgsea <- gseKEGG(geneList = res_gsea,
+                organism = 'hsa',
+                minGSSize = 10,
+                maxGSSize = 1000,
+                pvalueCutoff = 0.05, pAdjustMethod = "BH",
+                verbose = FALSE)
