When an object is about to be removed from R it is first deprecated and should include a call to
.Deprecated(new, package=NULL, msg, old = as.character(sys.call(sys.parent()))[1L])
- character string: A suggestion for a replacement function.
- character string: The package to be used when suggesting where the deprecated function might be listed.
- character string: A message to be printed, if missing a default message is used.
- character string specifying the function (default) or usage which is being deprecated.
.Deprecated("<new name>") is called from deprecated functions. The original help page for these functions is often available at
help("oldName-deprecated") (note the quotes). Functions should be listed in
help("pkg-deprecated") for an appropriate
base-deprecated and so on which list the deprecated functions in the packages.
