\description{
  These functions are provided for compatibility with older versions of
  \R only, and may be defunct as soon as the next release.
}
\usage{
trySilent(expr)
}
\arguments{
  \item{\dots}{named arguments with values coercible to a character string.}
}
\details{
  The original help page for these functions is often
  available at \code{help("oldName-deprecated")} (note the quotes).
  Functions in packages other than the methods package are listed in
  \code{help("pkg-deprecated")}.

  \code{trySilent(ex)} is a deprecated equivalent of \code{\link{try}(e,
    silent=TRUE)}; in \R programming it is typically more efficient and
    flexible to work with something like \code{\link{tryCatch}(ex,
      error = function(e) e)} instead. % possibly also 'function(e) NULL'
}
