\title{Map between TAIR Identifiers and PubMed Identifiers}
\description{
   org.At.tairPMID is an R object that provides mappings between
   TAIR identifiers and PubMed identifiers.
}
\details{
  Each TAIR identifier is mapped to a named vector of PubMed
  identifiers. The name associated with each vector corresponds to the
  TAIR identifier. The length of the vector may be one or greater,
  depending on how many PubMed identifiers a given TAIR identifier is
  mapped to. An \code{NA} is reported for any TAIR identifier that
  cannot be mapped to a PubMed identifier.

  Titles, abstracts, and possibly full texts of articles can be obtained
  from PubMed by providing a valid PubMed identifier. The pubmed
  function of annotate can also be used for the same purpose.

  Mappings were based on data provided by: Tair  
  ftp://ftp.arabidopsis.org/User\_Requests/LocusPublished.20090605.txt
