\title{Convert an annotated \code{GRanges} to a \code{data.frame}.}
\description{
  Converting a \code{GRanges} that might be annotated with some kind of results
  to a \code{data.frame} is useful, because it allows easier writing to file
  and viewing in other programs, like a spreadsheet program.
}
\usage{
  \S4method{annoGR2DF}{GRanges}(anno)
}
\arguments{
  \item{anno}{A \code{GRanges}, describing some genomic features.}
}
\details{
  The column name \code{seqnames} is changed to \code{chr}, and if all the
  strands are \code{*}, then the \code{strand} column is dropped.
}
\value{
  A \code{data.frame} of the annotation.
