It provides a set of functions designed to assist users in performing common data manipulation tasks, such as filtering rows, selecting columns, arranging data, and summarizing. This library is highly efficient and user-friendly, making it easier to work with large datasets by allowing you to write clearer and more concise code compared to base R functions.

1. filter(): Used to select rows based on certain conditions.
2. select(): Allows users to specify which columns to keep in the dataset.
3. arrange(): Helps in sorting the data based on one or more columns.
4. mutate(): Enables the creation of new columns or modification of existing ones.
5. summarize(): Used to create summary statistics of data.

Given these functionalities, it's clear that the primary purpose of the dplyr library is data manipulation, making it an essential tool in the data science toolkit for R users.
