What is R and why should you learn it?
R is a free and open-source software environment that was created by statisticians for statisticians. It has been widely used by researchers and professionals from various fields, such as biology, economics, psychology, and social sciences. R can perform a variety of tasks, such as data manipulation, statistical analysis, machine learning, web development, and graphical presentation.
R is a powerful language for statistical computing and graphics
One of the main strengths of R is its ability to handle complex and large data sets. R can read data from different sources, such as files, databases, APIs, or web pages. It can also perform various operations on data, such as filtering, sorting, aggregating, transforming, or summarizing. R has many built-in functions and packages that can help you perform common or advanced statistical tests, such as regression, hypothesis testing, clustering, or classification. Moreover, R can produce high-quality graphics and charts that can help you explore and communicate your data insights. You can customize your plots with different colors, shapes, sizes, or themes. You can also create interactive graphics that allow users to zoom in, hover over, or click on different elements.
R has many features and benefits for data analysis and visualization
Some of the features and benefits of R programming are:
It is open-source and free. You can download and use R without any fees or licenses. You can also modify and improve R according to your needs.
It is cross-platform and compatible with Windows, Mac OS, Linux, and other operating systems.
It is easy to access and adapt. You can install R in a few minutes and start coding right away. You can also customize your R environment with different settings, themes, or extensions.
It is a choice of many data scientists and analysts. R is one of the most popular languages for data science. It has a large and active community that supports and contributes to its development. It also has a rich collection of packages that provide additional functionalities for different domains.
It helps you develop your programming skills. R is an object-oriented and functional programming language that allows you to write concise and expressive code. It also has a robust debugging system that helps you find and fix errors in your code.
How to download and install R on your computer?
To use R on your computer, you need to download and install two components: the base R system and a graphical user interface (GUI) or an integrated development environment (IDE). The base R system provides the core functionality of the language, while the GUI or the IDE provides a more user-friendly interface for coding and running R scripts. The most common GUI for R is RStudio, which is also free and open-source. Here are the steps to download and install R and RStudio on your computer:
Choose your preferred CRAN mirror
CRAN stands for Comprehensive R Archive Network, which is a network of servers that host the R software and packages. To download R, you need to choose a CRAN mirror that is closest to your location. You can do this by visiting the official R website at and clicking on the "download R" link. You will see a list of CRAN mirrors from different countries. Select the one that suits you best.
Download the appropriate R version for your operating system
After choosing a CRAN mirror, you will be directed to a page where you can download the R version that matches your operating system. For example, if you are using Windows, you can click on the "Download R for Windows" link and then click on the "base" subdirectory. You will see a file named "R-x.x.x-win.exe", where x.x.x is the latest version of R. You can download this file and save it to your preferred location.

Run the R executable file and follow the instructions
Once you have downloaded the R executable file, you can run it by double-clicking on it. You will see a series of prompts that will guide you through the installation process. You can accept the default settings or change them according to your preferences. After the installation is complete, you will have an icon on your desktop or in your start menu that will launch the R console.
How to get started with R programming?
Now that you have installed R on your computer, you are ready to start coding. There are two ways to use R: through the R console or through an IDE like RStudio. The R console is a simple window that allows you to type and execute R commands. The IDE is a more advanced tool that provides features such as syntax highlighting, code completion, debugging, and project management. We recommend using an IDE for a better coding experience.
Launch the R console or an IDE
To launch the R console, you can simply click on the R icon on your desktop or in your start menu. You will see a window like this:
R version 4.1.1 (2021-08-10) -- "Kick Things" Copyright (C) 2021 The R Foundation for Statistical Computing Platform: x86_64-w64-mingw32/x64 (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY. You are welcome to redistribute it under certain conditions. Type 'license()' or 'licence()' for distribution details. Natural language support but running in an English locale R is a collaborative project with many contributors. Type 'contributors()' for more information and 'citation()' on how to cite R or R packages in publications. Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser interface to help. Type 'q()' to quit R. >
The > symbol is the prompt where you can type your commands. For example, you can type 2 + 2 and press enter to see the result:
> 2 + 2 [1] 4
To launch an IDE like RStudio, you need to download and install it from . You can choose the free desktop version for your operating system. After installing it, you can open it and see a window like this:
RStudio has four main panels: the source panel, where you can write and edit your scripts; the console panel, where you can run your commands; the environment panel, where you can see your variables and objects; and the files/plots/packages/help panel, where you can access different resources.
Learn the basics of R syntax and data structures
To start coding in R, you need to learn some basic syntax rules and data structures. Here are some of them:
R is case-sensitive. This means that x and X are different variables.
R uses # to indicate comments. Comments are lines of text that are ignored by the interpreter and are used to explain or document your code. For example, # This is a comment.
R uses ; or newline to separate commands. You can write multiple commands in one line by using ; or write one command per line. For example, x = 2; y = 3 or x = 2 y = 3.
R uses = or <- to assign values to variables. You can use either symbol to assign a value to a variable. For example, x = 2 or x <- 2.
R uses () to enclose arguments of functions. Functions are predefined or user-defined operations that perform a specific task. To use a function, you need to provide its name and arguments (i
