Hi,
 
 I want to fetch documents from PubMed. So first I get all the PMIDs and then use the "pubmed" function from the "annotate package". But does this function take care of the NCBI rule for waiting 3 seconds between queries? 
 
 Also I have a list of 718 PMIDs but the function retrieves only 377 of them? I don't understand why. Suggestions appreciated.
 
 Thank you and regards,
 Kaustubh
