warn_deprecated

Generates a warning when a deprecated function, argument, or active binding
is used or accessed. A warning will only be given once per session, and all
deprecation warnings can be suppressed by setting the option
<code>mlr3.warn_deprecated = FALSE</code>.
The warning is of the format
"what is deprecated and will be removed in the future."
Use the 'deprecated_binding()' helper function to create an active binding
that generates a warning when accessed.

Efficient, object-oriented programming on the
building blocks of machine learning. Provides 'R6' objects for tasks,
learners, resamplings, and measures. The package is geared towards
scalability and larger datasets by supporting parallelization and
out-of-memory data-backends like databases. While 'mlr3' focuses on
the core computational operations, add-on packages provide additional
functionality.

warn_deprecated function

<dl><dt>what</dt>
<dd>(character(1)) 
A description of the deprecated entity. This should be somewhat descriptive,
e.g. <code>"Class$method()"</code> or <code>"Argument 'foo' of Class$method()"</code>. 
The <code>what</code> is used to determine if the warning has already been given, so
it should be unique for each deprecated entity.</dd></dl>
