I want to implement id conversion using clusterProfiler. But I met a bug as following: I successfully library package org.Hs.eg.db, but I couldn't load it to implement ID conversion using function bitr in R package clusterProfiler. What's wrong with it? I couldn't figure it out and please help.

Did you load the package? Library() It would helpful for if you could provide some more information.

You should use the database without quotation marks:

orgDb=org.Hs.eg.db

Or you can try:

library(org.Hs.eg.db)
library(ensembldb)

genelist <- c("TSPAN6", "OPTN", "XIST")
ensembldb::select(
  x = org.Hs.eg.db,
  keys = genelist,
  keytype = "SYMBOL",
  columns = c("ENTREZID", "ENSEMBL")
)

====
  SYMBOL ENTREZID         ENSEMBL
1 TSPAN6     7105 ENSG00000000003
2   OPTN    10133 ENSG00000123240
3   XIST     7503 ENSG00000229807
====

Other nice packages to do these things are AnnotationDbi & biomaRt

Best, Tom
