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?
Thank you
