Hi, I want to use reutils to obtain the accession numbers of a query search in character format. When I use efetch, the accession number isn't in a character format, and I'm not sure if the number is accurate, because I get the error:
Error in file.exists(destfile) : object 'destfile' not found This is what I tried: UIDs<-esearch( "Methylation" ) accession_numbers = efetch(UIDs, rettype = "acc") How do I obtain only the accession number and is the number accruate?
