I am using an R package called 'PubMedWordcloud' and I get the following error when I try to retrieve the abstracts of a large number of PMIDs (Pubmed IDs):
> pmids <- getPMIDsByKeyWords(keys="candida albicans", n=3000) > abstracts=getAbstracts(pmids) Space required after the Public Identifier SystemLiteral " or ' expected SYSTEM or PUBLIC, the URI is missing Error: 1: Space required after the Public Identifier 2: SystemLiteral " or ' expected 3: SYSTEM or PUBLIC, the URI is missing
It appears that the problem is the number of PMIDs as I do not face the same issue when I try to retrieve a small number of PMIDs e.g. 10.
Anyone able to shed some light on the error message and how I can fix it?
