Welcome to the first lesson in our course on practical machine learning with the mtcars dataset in R. In this lesson, you will get hands-on experience with basic but essential data preprocessing and exploration techniques. These steps form the groundwork for any machine learning project, helping you understand your data and prepare it for modeling.

First, we need to load the mtcars dataset. The dataset is available in R by default, so you can load it directly using the data function.

Code:

There is no immediate output for this command, but it ensures the dataset is loaded into your R environment.

Next, to get a quick overview of the dataset, we generate summary statistics using the summary function. This will provide basic statistical metrics for each variable in the dataset.

Code:

Output:
