R is a programming language and open-source, cross-platform software environment for graphics and computing. Developed in 1995, it has become one of the main languages used for data science and machine learning today.
As of April 2020, R ranks 10th in the TIOBE and 7th in PYPL indexes. These are lists of most in-demand programming languages. R is popular not only among academics but global tech giants like Google and Microsoft as well.
In this article, you’ll find the easiest way to download R for Mac. We’ll also dig into everything you need to know to install RStudio, which is an integrated development environment (IDE). It makes using R much easier because of its user-friendly interface and a bunch of customization options. Let's get started!
R is a computer language. It’s a tool for doing the computation and number-crunching that set the stage for statistical analysis and decision-making. RStudio is an open source integrated development environment (IDE) for creating and running R code. It’s available in versions for Windows, Mac, and Linux. Although you don’t need an IDE in order. R-Studio is a powerful data recovery software that is able to process partitions formatted under various operating systems, such as Mac, Windows, Linux, and so on. The app can recover data from the disk regardless if the file system or the damage cause is known or not. This directory contains binaries for a base distribution and packages to run on Mac OS X (release 10.6 and above). Mac OS 8.6 to 9.2 (and Mac OS X 10.1) are no longer supported but you can find the last supported release of R for these systems (which is R 1.7.1) here.Releases for old Mac OS X systems (through Mac OS X 10.5) and PowerPC Macs can be found in the old directory.
R language is named after the first names of its developers — Ross Ihaka and Robert Gentleman.

How to prepare your Mac for R installation
The latest release R 3.6.3 runs smoothly on OS X 10.11 (El Capitan) and higher. Apple also notarizes this version, so it's fully compatible with Catalina.
Before installation, make sure you have at least 500 MB of free storage space on your Mac. To check it, go to the Apple menu in the top-left corner and choose About This Mac. Then, head over to the Storage tab.
If your space is a bit cluttered with files and data, you should consider clearing your hard drive before installing R.
All the junk files you have on your computer not only occupy gigabytes of space but also overload the CPU a lot. Heavy junk clusters can hide deeply in your system, so getting a little help with cleanup is the way to go.
CleanMyMac X by MacPaw is one of my favorite tools as it helps you manage your storage, maintain your Mac’s performance, and protect it from malware, all at once. Here's how to use it:
- Download and install CleanMyMac X — get your trial version here.
- Launch it and run the Smart Scan by pressing Scan.
- Once you see results, press Run to clear the junk.
You can also check out the Large & Old Files tab to remove the heaviest files that have been piling up on your Mac way too long. Now, your Mac is ready for installing R.
