\details{
  \code{category} has been an old-S function before there were factors;
  should be replaced by \code{\link{factor}} throughout!

  The new function \code{dev.print()} should now be used for saving
  plots to a file or printing them.

  \code{provide} and its object \code{.Provided} have been removed.
  They were never used for their intended purpose, to allow one
  package to subsume another.

  \code{getenv} has been replaced by \code{\link{Sys.getenv}}.

  \code{*.url} are replaced by calling \code{read.table}, \code{scan} or
  \code{source} on a \code{\link{url}} connection.

  \code{httpclient} was used by the deprecated \code{"socket"} method
  of \code{\link{download.file}}.

  \code{parse.dcf} has been replaced by \code{read.dcf}, which is much
  faster, but has a slightly different interface.

  \code{.Alias} provided an unreliable way to create duplicate
  references to the same object. There is no direct replacement. Where
  multiple references to a single object are required for semantic
  reasons consider using environments or external pointers. There are
  some notes on \url{http://developer.r-project.org}.

  \code{.Dyn.libs} and \code{.lib.loc} were internal variables used for
  storing and manipulating the information about packages with dynloaded
  shared libs, and the known \R library trees.  These are now dynamic
  variables which one can get or set using \code{\link{.dynLibs}} and
  \code{\link{.libPaths}}, respectively.

  \code{Machine()} and \code{Platform()} were functions returning the
  variables \code{\link{.Machine}} and \code{\link{.Platform}}
  respectively.

  \code{restart()} should be replaced by \code{try()}, in preparation
  for an exception-based implementation.  If you use \code{restart()} in
  a way that cannot be replaced with \code{try()} then ask for help
  on \code{r-devel}.

  \code{printNoClass} was in package \pkg{methods} and calls directly the
  internal function \code{print.default}.

  \code{codes} was almost always used inappropriately.  To get the
  internal coding of a factor, use \code{unclass}, \code{as.vector} or
  \code{as.integer}.  For \emph{ordered} factors, \code{codes} was
  equivalent to these, but for \emph{unordered} factors it assumed an
  an alphabetical ordering of the levels in the locale in use.

  \code{print.atomic} differed from \code{print.default} only in its
  argument sequence.  It is not a method for \code{print}.

  \code{La.eigen} has become the default for \code{\link{eigen}}.

  \code{tetragamma} and \code{pentagamma} have been replaced by
  \code{\link{psigamma}}.

  \code{package.description} has been replaced by
  \code{\link{packageDescription}} in \pkg{utils}.

  \code{loadURL} has been superseded by \code{\link{load}(url())}.
  
  \code{delay} has been replaced by \code{\link{delayedAssign}}. 
  Unevaluated promises should never be visible.

  \code{write.table0} was an \R-level version of \code{write.table}
  provided for temporary back-compatibility.

  \code{format.char} was an auxiliary function for \code{\link{formatC}}
  whose functionality (and more) is provided by \code{\link{format.default}}.

  \code{La.chol} and \code{La.chol2inv} became the default methods for
  \code{\link{chol}} and \code{\link{chol2inv}}.

  Functions \code{symbol.C} and \code{symbol.For} are for historical
  compatibility with S.  \code{symbol.C} just returns its argument
  unchanged, whereas \code{symbol.For} will map to lower case and
  append an underscore on those platforms (almost all) which do so for
  Fortran symbols.  These are no longer of any use in \R.

  \code{unix} was a \emph{deprecated} (since the 1990s) alternative to
  \code{\link{system}}, available for backwards compatibility.
