Hello.
I finally got running gseDO() from the DOSE package but, I just realised I can't or I don't know how to change the organism from human to Mouse. You can see the following script and the error.
y <- gseDO(geneList, nPerm = 500, minGSSize = 15, pvalueCutoff = 0.5, pAdjustMethod = "BH", OrgDb="org.Mm.eg.db", verbose = FALSE)
Error in gseDO(geneList, nPerm = 500, minGSSize = 15, pvalueCutoff = 0.5, : unused argument (OrgDb = "org.Mm.eg.db")
