R is an innovative, open-source programming language for machine learning and data science. Used for statistical analysis on datasets, it’s viewed as a different implementation of the S programming language. R provides an integrated development environment (IDE) for graphics and statistical computing and has become extremely popular in the past few years. R is one of the top 20 programming languages in the TIOBE index, which ranks the popularity and adoption of next-generation programming languages.

R is making inroads into many different business sectors, including finance, human resources, taxes, and even sports analytics. This popularity is due in part to the availability of business-specific packages that focus on topics such as econometrics, finance, and time series analysis. It also doesn’t hurt that the language is open-source.

Since it has many of the same industry-leading visualization features offered by Tableau and Cognos, R is being broadly adopted by scientists, engineers, and even professionals who don’t have a computer science background. Internet companies, including Uber, Google, Airbnb, Netflix, and Facebook, use R for its rich visualization and reporting capabilities. Leading academic institutions, including Harvard and MIT, are using R for research purposes.

R Language’s Popularity 

Major businesses use R programming language extensively, as it has considerable advantages over other programming and reporting languages, such as ease of use and simplification of analytics.

For instance, it has many innovative algorithms such as Keras and TensorFlow, resources that are needed to implement deep learning models. It also has xgboost, an algorithm that consistently wins machine learning competitions on Kaggle.

When compared to other programming languages like Python and SAS, its advantage includes the ability to simplify the creation of business-ready reports and machine learning-powered web applications. If you’re from a non-computer background but are looking into the data science profession, then you need to learn R.


What is R Programming?

Ross Ihaka and Robert Gentleman invented the programming language known as R in 1995 at the University of Auckland, New Zealand. The R Development Core Team now backs it up, while developing additional features that keep the language competitive and on par with other programming languages. 

Here’s a glimpse of what R can offer:

  • You can use R to create objects, functions, and packages, just like any other programming language.
  • It’s an independent platform so that it can be installed and used on any operating system. 
  • R is made up of a group of libraries explicitly designed for data science.
  • The language is not only a statistical package but is open-source, which means anyone can inspect the source code and modify it as necessary.
  • The libraries are mostly written in R. However, C, C++, and Fortran codes can be used for heavy computational tasks.
  • R allows you to interact with many data sources, connecting to many databases and statistical packages, including SAS and SPSS.
  • R has a large fan base with a growing community of enthusiastic professionals, ranging from business to academia.
  • Users interact with R through a command-line interface. There are numerous graphical user interfaces available, including RStudio, allowing developers or users to create various reports and analytical dashboards.

Why Learn R Programming?

R provides an edge for anyone who is an analytics professional, engineer (mechanical, industrial, chemical), or who has another non-computer science background and wants to excel in the field of data science.

R is an interpreted language so that you can run the code without a compiler. Since it’s vector-based, R is faster and more powerful than most other programming languages (including Python and SAS). This means users or developers can individually add functions to a vector without adding in a loop. 

Learning R is useful for communicating the value of data and its insights throughout your organization, and you can develop reports for all levels. R is predominantly used for data analysis, machine learning, and statistical inference, but has many uses. Simply stated, it provides a wide array of tools to capture the right model for your data.
