Introduction to R

Welcome to the first lecture on R Basics! In this lecture, we will provide an overview of R, its history, and its applications. Whether you’re new to programming or transitioning from another language, this guide will help you understand the basics of R and how it can be used for data analysis, statistical computing, and graphics.

What is R?

R is a powerful programming language and software environment used for statistical computing and graphics. It is widely used among statisticians, data analysts, and researchers for data analysis and visualization. R provides a wide variety of statistical and graphical techniques, including linear and nonlinear modeling, statistical tests, time-series analysis, classification, clustering, and more.

History of R

Brief History

R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, in the mid-1990s. It is an open-source implementation of the S programming language, which was developed at Bell Laboratories by John Chambers and colleagues. Since its inception, R has grown in popularity and has become a standard tool for data analysis in academia and industry.

Why Use R?

There are several reasons why R is a popular choice for data analysis and statistical computing:

  • Open Source: R is free to use and open-source, which means anyone can contribute to its development and improvement.
  • Comprehensive: R has a vast collection of packages available for various types of data analysis and visualization.
  • Community Support: R has a large and active community of users who contribute to forums, mailing lists, and online resources.
  • Flexibility: R can be integrated with other programming languages and tools, such as Python, SQL, and Hadoop.
  • Visualization: R excels in creating high-quality plots and graphs, making it easier to visualize and interpret data.
