\description{Functions to obtain the reverse and reverse complement of a
  sequence}
\usage{
reverseSeq(seq)
revcompDNA(seq)
revcompRNA(seq)
}
\arguments{
  \item{seq}{Character vector.  For \code{revcompRNA} and
  \code{revcompDNA} the sequence should consist of appropriate letter
  codes: \code{[ACGUN]} and \code{ACGTN}, respectively.}
}
\details{
  The function reverses the order of the constituent
  character strings of its argument.
}
\value{
  A character vector of the same length as \code{seq}.
