In this article, we will explain what R is, why you should use it, and how to download and install it on your Windows, Mac, or Linux system.
What is R and why use it?
R is a free software environment for statistical computing and graphics
R is an open source project that was started in 1995 by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand. It is based on the S language, which was developed at Bell Labs in the 1970s. R provides a flexible and powerful platform for data manipulation, analysis, modeling, visualization, and reporting. It can handle various types of data, such as vectors, matrices, lists, data frames, factors, and more. It also supports many programming paradigms, such as functional, object-oriented, and procedural.
