A more sophisticated location model
The locations dataset records Brett's location every hour for 13 weeks. Each hour, the tracking information includes the daytype (weekend or weekday) as well as the hourtype (morning, afternoon, evening, or night).
Using this data, build a more sophisticated model to see how Brett's predicted location not only varies by the day of week but also by the time of day. The dataset locations is already loaded in your workspace.
You can specify additional independent variables in your formula using the + sign (e.g. y ~ x + b).
The naivebayes package has been pre-loaded.

Istruzioni dell'esercizio
- Use the R formula interface to build a model where location depends on both
daytypeandhourtype. Recall that the functionnaive_bayes()takes 2 arguments:formulaanddata. - Predict Brett's location on a weekday afternoon using the data frame
weekday_afternoonand thepredict()function. - Do the same for a
weekday_evening.
