How to use the built-in data packages in R language?

In R language, you can follow these steps to use the built-in data packages:

1. To check the available package list, use the functions library() or require(). For example, to see if the datasets package is available, you can enter library(datasets) or require(datasets).
2. Load data package: Use the functions library() or require() to load a specific data package. For example, to load the datasets package, you can type library(datasets) or require(datasets).
3. After loading the data package, you can use the data included in the package. For instance, to access the mtcars dataset in the datasets package, simply type mtcars to view the contents of the dataset.
4. To view the help documentation for a package: in order to understand the functions and detailed information within a package, you can use the help() function or the “?” symbol, providing the package name as a parameter. For example, to view the help documentation for the “datasets” package, you can enter help(datasets) or ?datasets.

Before using a package, you need to install the corresponding package. You can use the install.packages() function to install the required package. For example, to install the datasets package, you can type install.packages(“datasets”).
