Hello

I tried to use the ReactomePA package and everything looks good, but finally I got the following error:

> viewPathway("E2F mediated regulation of DNA replication", readable=TRUE, foldChange=CL5_geneList)
'select()' returned 1:1 mapping between keys and columns
'select()' returned 1:1 mapping between keys and columns
Error: !any(duplicated(names(foldChange))) is not TRUE

Error: !any(duplicated(names(foldChange))) is not TRUE

your geneList, CL5_geneList, contains duplicated name.
