\title{Map custom probeset IDs to strand on chromosomes}
\description{
 gahgu133plus2STRAND is an R environment that provides mappings between a
 custom probeset identifier and the strand of gene onto corresponding chromosome.
}
\details{
  Each identifier maps to a gene strand.
  If the gene strand is unknown,
  the vector will contain an \code{NA}.

  Mappings were based on data provided by:
