What is R?
R is the most powerful and widely used programming language for computational statistics, visualization, and data science. Many data scientists and statisticians use R to solve their problems in the data analytics field in all the sections from computational biology to quantitative marketing. R is a GNU project which is more like the S language. Therefore, it is considered a dialect of the S language.
R provides a wide range of statistical and graphical techniques. As a result, r is highly extensible and offers a lot of choices for research people. R is free software on various platforms like UNIX, Windows, Linux, and MacOS. R is also the most popular and successful language with some powerful features. It is used by top-rated companies like Google, Facebook, Shell, Merck, Bank of America, Pfizer, and LinkedIn.
R is an integrated suite of software facilities developed for data analysis, statistical modeling, simulation, and graphics. R is a simple and effective language that includes conditionals, loops, user-defined recursive functions, and input and output facilities. R includes the following.
- effective data handling and storage facility
- set of operators for calculation of arrays
- a huge integrated collection of intermediate tools for data analysis
- graphical facilities to be displayed either on screen or hardcopy
- allows users to add additional functionality
- C, C++, and Fortran code can be linked to R and called at run time
- R can be extended through packages easily
- R has its Latex-like documentation format, which supplies comprehensive documentation.
Why use R Analytics Tool?
There is a lot of software available for data analysis today, but still, R stands ahead of all the other tools. There are many reasons why data scientists choose R. Few reasons are listed below.
R is free
R is an open-source project which you can download and use for free. You don’t have to worry about subscription fees, license fees, license renewals, or user limits as R is an open-source software you can inspect and make changes to the code as you like. So many experts have contributed to R in such a way that now it benefits millions of people who use R today.
R is not just a statistical package; it is a language.
R is an easy language to learn. In R, data analysis is done by writing functions and scripts, not just in simple clicks. It offers a natural and expressive way for data analysis. There are many advantages of learning this language. It is the most interactive language when compared with other programming languages. R provides an innovative way of data analysis and leads to better results that otherwise would not have been done. A script records all your work which can be re-run at any time. These scripts also make it easy for you to automate a sequence of tasks that can be integrated into other processes.
Data analysis techniques at your fingertips
R contains all the traditional and recently developed data manipulation techniques. It also offers you different statistical models and charts that all the data scientists feel are essential to them. You can easily download any method free of cost.
Powerful graphics and Data Visualization
One of the main features of R is the visualization of data through charts and graphs. R offers special tools for producing graphics, from information provided in the form of bar charts and scatter plots to multi-panel Lattice charts. Experts in data visualization like Bill Cleveland and Edward Tufte also believe in R’s graphical system. Because of its excellent graphical properties, R is used in reputed places like New York Times, the Economist, and the FlowingData Blog.
Faster and better results
R stands ahead of the usual black-box procedures of other data analytics tools. R is designed especially for data analysis to create faster results than other statistical software programs. It also offers you to mix and match models for better results. Finally, the scripts of R are automated, which helps you to deliver reproducible research.
Cutting edge statistics with R
Leading data scientists and researchers worldwide use R for statistics, machine learning, and predictive modeling. As a result, R has a lot of packages that are not available in any other statistical tool in the data analysis market. There are more than 2000 packages available in the R language in every domain for free download. And more packages are added frequently. Because of such packages, R is widely used in fields like finance, genomics, and many other fields. One example of such a package is “glmnet.” This exclusive modeling package handles the prediction of interval and categorical dependent variables efficiently.
Flexible data analysis tool
R has built a standard data analysis tool that includes accessing data in various formats, data manipulation, and traditional and modern statistical models. The statistical models include regression, ANOVA, GLM, tree models, and others. All the statistical tools are available in an object-oriented framework that will help you to extract only the information you need from the results. It will thus reduce unwanted statistics, and you don’t have to produce a cut-and-paste static report.
If you have any R-related questions, there is an answer for you on the web. There are a lot of community resources available on the internet for R. R has thousands of contributors and more than two million users from around the world. This is one of the main reasons you can find answers to all your R-related questions on the web.
R is an open-source community, and many people contribute directly to the R language. It does not have a pre-defined set of codes. Instead, you can use codes that others contribute to the R community. You can also extend the R functions. R mingles easily with applications like MySQL database, Apache web server, Google maps, and others.

Why does R Analytics Tool get so much attention?
Many languages are used for data analysis, but most people prefer using R for their business. The reasons why R is preferred more than other languages are listed below.
- More interactive language – Interactivity and Language are more important for data analysis. R, in other words, is an interactive language, making it more special than other languages.
- Data structures – R also offers an excellent way to create data structures. You don’t need to put all your data in a set of pre-defined structures. You can create your structure and put your data in a natural form.
- Excellent graphical properties – Human brains are more attracted to pictures than numbers or text. R gives you a high-quality graphical representation of data.
- Missing values – Real data always have missing values. R has several functions that will help you deal with missing values. Missing values are an integral part of R.
- Lots of packages – R has many packages that allow you to add your own functionality to make it unique. These packages help you do extraordinary things with R.
- Support and Community – R has a very supportive community that helps improve data analysis through R language.
- First-class objects – Objects here mean functions like mean and median. You can shift between the functions more easily in the R language.
- Vector oriented – Objects in R are considered as a whole rather than treating it as a collection of individual numbers. For example, if you want to change the volume from liters to milliliters, then a simple code change has to be done.
- Flexibility – R does not compel you to work only within its language. You can mix different tools and select the best tool for each task. You can also call C and C++ functionality.
- Changes made easy – The codes written in the R language are accessible to the users. If any minor change has to be done to the task, you can change the code in a shorter period.
