I have performed RNAseq analysis using the NCBI latest genome. While converting the geneids to gene symbols there are many NA in the gene Symbol , can anybody guide me regarding this
The code i am using for conversions is the map function:
mapIds(org.Hs.eg.db, keys = row.names(sorted_results),column ="SYMBOL",keytype = "ENTREZID")
Thanks
