What is R? 

R is a popular open-source programming language that is widely used for Statistical Computing, data analysis, and graphics. It is a powerful tool that provides a wide range of statistical and graphical techniques, including linear and nonlinear modeling, time-series analysis, clustering, and many more. R was first developed by Ross Ihaka and Robert Gentleman in the early 1990s at the University of Auckland, New Zealand, and since then, it has become a popular choice among data scientists, statisticians, and researchers worldwide. 

Overview of R 

R is a high-level programming language that is specifically designed for statistical computing and data analysis. It provides an interactive environment for data analysis, where the user can execute code and see the results in real-time. It is an interpreted language, which means that the code is executed directly without the need for compilation. This makes it simple to navigate even for those who are not programmers. It provides a wide range of packages and libraries that can be used to extend its functionality. It is also highly extensible, which means that users can easily create their own packages and libraries. 

Applications of R 

R has a wide range of applications in various fields, including finance, healthcare, marketing, social sciences, and many more. Let’s take a closer look at some of the applications of R:
