So far I was able to fetch the Gene Name and Gene Entrez for my genes of interest with
> top0$Gene_Name <- mapIds(org.Hs.eg.db, > keys=ens.str, > column="SYMBOL", > keytype="ENSEMBL", > multiVals="first") top0$Gene_Entrez <- mapIds(org.Hs.eg.db, keys=ens.str, column="ENTREZID", keytype="ENSEMBL", multiVals="first")
But I am struggling to get the Chromosome information for these ones. Does anyone has an idea how I could do that?
Thank you very much, Bine
