Grid search with range of hyperparameters

In chapter 1, you learned how to use the expand.grid() function to manually define a set of hyperparameters. The same function can also be used to define a grid with ranges of hyperparameters.

The voters_train_data dataset has been loaded for you, as have the caret and tictoc packages.
