fmath error in clusterProfiler package

Question

[maleknias]

I tried to do Gene set enrichment analysis but I encountered the following error message: library(clusterProfiler)

genelist <- read.table("Data/DE-geneSymbol.txt", header = TRUE, stringsAsFactors = FALSE)

head(genelist)

  KEGGGeneID GeneSymbol  NCBI

1   hsa:3831       KLC1  3831

2  hsa:11274      USP18 11274
3  hsa:81614      NIPA2 81614

5   hsa:1349      COX7B  1349
6   hsa:7155      TOP2B  7155

 genelist <- genelist[,3]

genelist = sort(genelist, decreasing = TRUE)

head(genelist)

Could you please help me?

Dear all

I solved it. First I prepare my geneList by:

So the error removed!!
