set_engine() is used to specify which package or system will be used
to fit the model, along with any arguments specific to that software.
set_engine(object, engine, ...)
A model specification.
A character string for the software that should be used to fit the model. This is highly dependent on the type of model (e.g. linear regression, random forest, etc.).
Any optional arguments associated with the chosen computational
engine. These are captured as quosures and can be
An updated model specification.
