\begin{Description}\relax
ratLLMappingsPMID2LL maps PubMed identifiers to Entrez Gene identifiers for genes that have
been cited by publications represented by the PubMed identifiers
\end{Description}
\begin{Details}\relax
This is an environment object containing key and value pairs. Keys are
PubMed identifier and values are Entrez Gene identifiers representing genes cited by
publications corresponding to the PubMed identifiers. Values are vectors of
length 1 or more depending on whether a PubMed identifier can be mapped to one
or more Entrez Gene identifiers.

Mappings were derived from data provided by:

        xx <- as.list(ratLLMappingsPMID2LL)
        if(length(xx) > 0){
                # Get the value of the first key
                xx[[1]]
                # Get the values for a few keys
                if(length(xx) >= 3){
