Deprecated

When an object is about to be removed from R it is first deprecated and should include a call to .Deprecated.

Syntax

R Copy

.Deprecated(new, package=NULL, msg,
            old = as.character(sys.call(sys.parent()))[1L])

Arguments

Parameter	Description
new	character string: A suggestion for a replacement function.
package	character string: The package to be used when suggesting where the deprecated function might be listed.
msg	character string: A message to be printed, if missing a default message is used.
old	character string specifying the function (default) or usage which is being deprecated.

Details

.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 pkg, including base. .Deprecated signals a warning of class deprecatedWarning with fields old, new, and package.
