\title{An Sweave driver to retrieve code chunks}
\description{
  A driver function for \code{Sweave} which will provide the user with
  code chunks from a vignette file within R.  Functionality is very
  similar to that provided by \code{Stangle} except that an R object is
  returned as opposed to the chunks being written to a file.
}
\usage{
tangleToR()
}
\value{
  An object of type \code{chunkList} is returned, which contains the
  code chunks from the vignette file.
}
