R Data Set

R provides various datasets for practice and analysis, accessible through packages like datasets. You can load these datasets to explore and analyze them using built-in R functions.

Key Topics

Loading a Data Set

You can load datasets from the datasets package using the data() function.

# Loading the 'mtcars' dataset
data("mtcars")

# Displaying the first few rows
head(mtcars)

Output:

The first few rows of the 'mtcars' dataset.

Code Explanation: The data() function loads the mtcars dataset, and head() displays the first few rows.

Exploring a Data Set

Use functions like summary() and str() to explore the structure and summary statistics of a dataset.

# Exploring the dataset
summary(mtcars)
str(mtcars)

Output:

Summary statistics and structure of the 'mtcars' dataset.

Code Explanation: The summary() function provides summary statistics, and str() shows the structure of the mtcars dataset.
