auto_ml()
defines an automated searching and tuning process where
many models of different families are trained and ranked given their
performance on the training data.
There are different ways to fit this model, and the method of estimation is chosen by setting the model engine. The engine-specific pages for this model are listed below.

Details
This function only defines what type of model is being fit. Once an engine
is specified, the method to fit the model is also defined. See
set_engine()
for more on setting the engine, including how to set engine
arguments.
The model is not trained or fit until the fit()
function is used
with the data.
Each of the arguments in this function other than mode
and engine
are
captured as quosures. To pass values
programmatically, use the injection operator like so:
value <- 1
auto_ml(argument = !!value)
