R is a prominent data science programming language that is utilised in a variety of companies and universities. R has become the preferred computing environment for many data scientists today since it is open-source, simple to use, and capable of handling complicated data and statistical computations.

With the rising prevalence of data in our everyday lives, new and improved methods to evaluate the flood are required. Traditionally, there have been two extremes: lightweight, individual analysis using programmes such as Excel or SPSS, and heavy-duty, high-performance analysis developed with C++ and the like. As personal computers became more powerful, a middle ground that was both interactive and sturdy emerged. An exploratory analysis performed by a person on his or her own computer may swiftly be turned into something meant for a server, backing complex business operations. R, Python, and other programmed languages are experts in this field. R was developed in 1993 by Robert Gentleman and Ross Ihaka of the University of Auckland from S, which was developed by John Chambers at Bell Labs. It is a high-level language that was designed to be executed interactively, with the user issuing a command, receiving a result, and then issuing another command. Since then, it has grown into a language that can be embedded in systems and used to solve complicated issues. R can easily create stunning visuals and reports in addition to processing and analysing data. It is currently utilised as a whole stack for data analysis, including data extraction and transformation, model fitting, inference and prediction, and displaying and presenting findings.
Since the late 2000s, R's popularity has surged as it has moved beyond academics and into finance, marketing, drugs, politics, genomics, and many other sectors. Its new customers frequently migrate from low-level, compiled languages like C++, other statistical tools like SAS or SPSS, and Excel, the 800-pound monster. During this time, the number of add-on package libraries containing prewritten code that increase R's capability skyrocketed. While R might be scary to novices, particularly those without programming expertise, I have found that programming analysis, rather than pointing and clicking, quickly becomes lot easier, more convenient, and more dependable. My objective is to make the learning process easier and faster.
R for Everyone organises material in a way that I wish I had learned when learning R in graduate school. Finally, the material of this book was created in collaboration with the data science course that the author teaches at Columbia University. It is not intended to cover every last element of R, but rather to cover the 20% of capability required to do 80% of the task. |
