We all know that the exponential increase in data has led to the rise in demand for specialized data scientists. This calls for advanced data analytics tools that can help is developing insights from the data. *R is an important tool for Data Science*.

It is highly popular and is the first choice of many statisticians and data scientists alike. But what makes R so popular? Why and How to use R for Data Science?

With this article, we will try to solve your queries and show you the features of R, which makes R highly suitable language for Data Science.

## 1. What is R?

*R programming language is one* *that allows statistical computing that is used widely by the data miners and statisticians for data analysis*. It was developed in **1995** by **Ross Ihaka** and **Robert Gentleman**, where the name ‘R’ was derived from the first letters of their names.

*R is a popular choice in data analytics and data science for statistical computing and graphical technique*s.

R contains a collection of over 10,000 packages in its **CRAN repository**. These packages appeal to various statistical applications. For beginners, *R may offer a steep learning curve. But while the syntax of R may be easy to understand.*

It is an expressive tool that is used to implement statistical learning. Therefore, a user without knowledge of statistics may not be able to get the best out of R.

## 2. Why We Choose R for Data Science?

Data Science has emerged as the most popular field of the 21st century. It is because there is a pressing need to analyze and construct insights from the data. Industries transform raw data into furnished data products.

In order to do so, it requires several important tools to churn the raw data. R is one of the programming languages that provide an intensive environment for you to analyze, process, transform and visualize information.

It is the primary choice for many statisticians who want to involve themselves in designing statistical models for solving complex problems.

**R contains a sea of packages** that appeal to all the forms of disciplines like astronomy, biology, etc. While R was originally used for academic purposes, it is now being used in industries as well.

*R is an advanced language that is used for performing complex statistical modeling*. Moreover, R also provides support for operations on arrays, matrices, and vectors. **R is famous for its graphical libraries** that allow the users to delineate aesthetic graphs and make them intractable for the users.

Moreover, R allows its users to develop web-applications using R Shiny, which is used for embedding visualizations in web-pages and provides a high level of interaction to the users.

Furthermore, *data extraction is an important part of data science*. In order to do so, R provides the option of interfacing your R code with database management systems.

In addition to this, **R provides you with several options of advanced data analytics** like the development of prediction models, **machine learning algorithms**, etc. R also provides several packages for image processing

## 3. Features of R

There are important features of R, which we should discuss to understand the role of R for Data Science.

**Open-source –**R is an open-source tool which means that you can download and modify the code and even develop your own libraries. It is also free to use.**A complete language**– While R is generally perceived to be a programming language for statistics, it also contains several features of an Object Oriented Programming language.**Analytical support**– With R, you can perform analytical operations through its wide range of support libraries. You can clean, organize, analyze, visualize your data and can also create predictive models.**Supports extensions**– R allows the developers to write their own libraries and packages and facilitate these packages as distributed add-ons. This makes*R a developer-friendly language*that allows changes and updates in its tools.**Facilitates interaction with databases**– It consists of several add-on packages that connect R with databases like RODBC package, Open DataBase Connectivity Protocol (ODBC) and the ROracle package that allows interaction with Oracle databases. The R programming language also provides extensions of MySQL as RMySQL.**Extensive community support**– It has an active community which is further bolstered by the fact that R is an open-source programming language. This makes R an ideal choice for many. R provides many worldwide boot camps and workshops.**Simple and easy to understand**– While many may argue that R offers a steep learning curve for the beginners, it is so because*R is a statistical language*. In order to use R at its best, you need to have experience with statistics. However, R has an easy to understand syntax. This allows you to remember and understand R properly.

## 4. Important Packages of R for Data Science

Packages in R plays an important role, let’s check some **popular and useful Packages –**

### 4.1 ggplot2

**R is most famous for its visualization** library ggplot2. It provides an aesthetic set of graphics that are also interactive. Ggplot2 comes with many extensions that increase the usability and experience.

### 4.2 Tidyr

Tidyr is an R package that allows you to clean and organize your data. Tidyr treats the data through the following two properties –

- Every column is treated as a variable.
- Every row is an observation

Using tidyr, you can use three main functions – gather(), spread(), separate() to organize your data into rows and columns.

### 4.3 Dplyr

Perhaps the most important R library, *dplyr allows you to organize, manage and wrangle data*. An important feature of dplyr is that it uses a declarative syntax that is easy to remember. Dplyr facilitates various operations like select, modify, filter, mutate, etc.

## 5. Why is R Important in Data Science?

Some of the important features of R for data science application are –

- R provides various important
**packages for data wrangling**like dplyr, purrr, readxl, google sheets, datapasta, jsonlite, tidyquant, tidyr etc. - R provides
**extensive support for statistical modelling**. Since Data Science is statistics heavy, R is an ideal tool for implementing various statistical operations on it. - R is an
**attractive tool for various data science application**s because it provides aesthetic visualization tools like ggplot2, scatterplot3D, lattice, highcharter etc. - R is heavily used in data science applications for ETL (Extract, Transform, Load). It provides an interface for many databases like SQL and even spreadsheets.
- Another important ability of
**R is to interface with NoSQL databases and analyze unstructured data**. This is very useful in Data Science applications where a pool of data has to be analyzed. - With R,
**data scientists can apply machine learning algorithms**to gain insights about future events. There are various packages like rpart, CARET, randomForest, and nnet.
