\begin{Description}\relax
PubMed \url{http://www.ncbi.nlm.nih.gov/PubMed/} includes over 14
million citations for biomedical articles back to the 1950's. Each
article has a unique PubMed identifier. YEASTPMID maps probe
identifiers to PubMed identifier for publications that cited the genes
represented by the probe identifiers
\end{Description}
\begin{Details}\relax
Titles, abstracts, and possibly full texts of articles can be obtained
from PubMed by providing a valid PubMed id. The pubmed function of
annotate can also be used for the same purpose.

Mappings were based on data provided by:

\begin{ExampleCode}
    # Convert the environment to a list
    xx <- as.list(YEASTPMID)
    if(length(xx) > 0){
        # The probe ids for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
        if(interactive() && !is.null(xx[[1]]) && !is.na(xx[[1]])
           && require(annotate)){
            # Gets article information as XML files
            xmls <- pubmed(xx[[1]], disp = "data")
            # Views article information using a browser
            pubmed(xx[[1]], disp = "browser")
        }
