  The first block of functions should be replaced by direct access to
57 
  the slots, or by use of higher-level alternatives.

  The functions and corresponding slots are:
60 
  \tabular{ll}{
61 
    \code{getAccess} \tab \code{"access"} \cr
62 
    \code{getClassName} \tab \code{"className"} \cr
63 
    \code{getClassPackage} \tab \code{"package"} \cr
64 
    \code{getExtends} \tab \code{"contains"} \cr
65 
    \code{getProperties} \tab \code{"slots"} \cr
66 
    \code{getPrototype} \tab \code{"prototype"} \cr

  \code{getAllMethods} replicated the behavior of
72 
  \code{\link{getMethods}}, which should be called instead to obtain
73 
  approximately the old behavior of \code{getAllMethods}.  However, a
74 
  better substitution is to use \code{\link{findMethods}}, which
75 
  returns a simpler structure.

  \code{mlistMetaName} was a utility to  return the mangled
78 
  name for the object that stored the \code{MethodsList}
79 
  representation of the methods for a particular generic function,
80 
  typically in the environment of a package.  These objects are no
81 
  longer used.
44805 jmc 82 
 
44922 ripley 83 
  \code{removeMethodsObject} removed the metadata object containing
84 
  methods for \code{f}.
44924 ripley 85 
 
86 
  \code{seemsS4Object} was similar to \code{\link{isS4}} and superseded
87 
  by the introduction of the S4 bit in \R 2.4.0.
46616 ripley 88 
 
89 
  \code{allGenerics} is superseded by \code{\link{getGenerics}}.

  \code{trySilent(ex)} was a deprecated equivalent of \code{\link{try}(e,
92 
    silent=TRUE)}; in \R programming it is typically more efficient and
93 
  flexible to work with something like \code{\link{tryCatch}(ex,
94 
    error = function(e) e)} instead.
61433 ripley 95 
 
60851 ripley 96 
  The functions \code{traceOn} and \code{traceOff} have been replaced by
97 
  extended versions of the functions \code{\link{trace}} and
98 
  \code{\link{untrace}}.
