The dataset ToyotaCorolla. csv contains data on used cars on sale during the late summer of 2004 in the Netherlands. It has 1436 records containing details on 38 attributes, including Price, Age, Kilometers, HP, and other specifications. a. Explore the data using the data visualization capabilities of R. Which of the pairs among the variables seem to be correlated?
b. We plan to analyze the data using various data mining techniques described in future chapters.
Prepare the data for use as follows:
i. The dataset has two categorical attributes, Fuel Type and Metallic. Describe how you would convert these to binary variables. Confirm this using Râs functions to transform categorical data into dummies.
ii. Prepare the dataset (as factored into dummies) for data mining techniques of supervised learning by creating partitions in R.
