[BioC] From Unigene IDs to PubMed abstracts

[John Zhang]

Here is an example: 

library("humanLLMappings")
library("annotate") ## developmental version 
library("XML")
llIds <- lookUp(c("Hs.390608", "Hs.444776"), "humanLLMappings", "UG2LL")
pmids <- lookUp(unlist(llIds), "humanLLMappings", "LL2PMID")
abs <- pubmed(unlist(pmids), "data")
abs <- getPMInfo(abs)
# The first abstract in the list
abs[[names(abs)[[1]]]][["abstract"]]
