I tried to map some Human genes to KEGG pathways using pathview library. However, an error occurred.  Can someone point out the error?

    geneList = read.table("list.txt", sep="\t", header=TRUE)
    hsa04110 <- pathview(  = geneList,
            = "hsa04110",
                     species    = "hsa",
                     limit      = list(gene=max(abs(geneList)), cpd=1))


'list.txt' file contains human gene ids and values. For example,

id    fc
hsa04110    1
hsa04114    2
hsa04218    3
