To download R for macOS, you will need to visit the official website of the R Project for Statistical Computing. This is the organization responsible for the development and maintenance of R. By obtaining R from the official website, you can ensure that you are getting the latest stable version of the software and that it is safe and secure to use.

Once you are on the R Project website, navigate to the download page. On this page, you will find various options for downloading R, including builds for different operating systems, source code, and pre-built binaries. Locate the section labeled “Download R for macOS” and select the appropriate version for your system. The available versions will depend on the latest release of R and your macOS version.

After selecting the correct version, you will be taken to a page where you can download the R pkg file. This file contains the R installer for macOS. The size of the file is typically around 100 MB, so it may take a few minutes to download depending on your internet speed.

Once the download is complete, you can proceed with the installation process. Double-click on the downloaded pkg file to launch the installer. Follow the on-screen instructions to complete the installation. During the installation, you may be prompted to select a destination folder for R. It is recommended to keep the default location, which is typically in the Applications folder.

After the installation is complete, you can verify that R is properly installed by opening Terminal and typing “R”. This should launch the R console. If R opens successfully, it means that the installation was successful and you can start using R on your Mac.

Select macOS: Choose the macOS installer from the download page.

On the R Project download page, you will find various options for downloading R, including builds for different operating systems, source code, and pre-built binaries. To obtain the correct installer for your Mac, you need to select the macOS version that is appropriate for your system.

  • Identify Your macOS Version:

    Before downloading the R installer, you need to know which version of macOS you are running on your Mac. To find this information, click on the Apple menu in the top-left corner of your screen and select “About This Mac”. A window will appear showing the name and version of your macOS operating system.

  • Choose the Correct Installer:

    Once you know your macOS version, you can select the appropriate R installer from the download page. Look for the section labeled “Download R for macOS” and find the version that matches your macOS version. For example, if you are running macOS Monterey 12.6, you would select the installer labeled “R-4.2.0.pkg” or later.

  • 64-bit or 32-bit Installer:

    In most cases, you should choose the 64-bit installer. The 64-bit version of R is more powerful and can handle larger datasets and more complex analyses. However, if you have an older Mac that is not compatible with 64-bit software, you may need to download the 32-bit installer instead.

  • Download the Installer:

    Once you have selected the correct installer, click on the download link to start downloading the pkg file. The file size is typically around 100 MB, so it may take a few minutes to download depending on your internet speed.

After the download is complete, you can proceed with the installation process. Double-click on the downloaded pkg file to launch the installer. Follow the on-screen instructions to complete the installation. During the installation, you may be prompted to select a destination folder for R. It is recommended to keep the default location, which is typically in the Applications folder.

Install Package: Run the downloaded pkg file to install R.

Once you have downloaded the R pkg file for macOS, you can proceed with the installation process. Double-click on the downloaded file to launch the installer. A window will appear guiding you through the installation steps.

In the installer window, you will see a welcome message and a button labeled “Continue”. Click on “Continue” to proceed to the next step. You may be prompted to enter your Mac’s administrator password to allow the installation process to make changes to your system.

Next, you will see a license agreement. Read through the agreement and select “Agree” to accept the terms and conditions. Click on “Continue” to proceed.

The installer will then ask you to select a destination folder for R. It is recommended to keep the default location, which is typically in the Applications folder. However, you can choose a different location if you prefer. Click on “Install” to start the installation process.

The installation process may take a few minutes to complete. Once it is finished, you will see a message saying “Installation was successful”. Click on “Close” to exit the installer.

Verify Installation: Open Terminal and type “R” to launch R.

After installing R on your Mac, you can verify that it is properly installed and working correctly by launching the R console.

  • Open Terminal:

    To launch the R console, you will need to open a Terminal window. Terminal is a command-line interface application included with macOS. You can find it in the Utilities folder within the Applications folder. Alternatively, you can press Command+Space to open Spotlight Search, type “Terminal”, and press Enter.

  • Type “R”:

    Once the Terminal window is open, type the letter “R” and press Enter. This will attempt to launch the R console.

  • Check for R Welcome Message:

    If R is installed and working correctly, you should see a welcome message and the R prompt (“>”) in the Terminal window. The welcome message typically includes information about the version of R that you have installed.

  • Try Basic R Commands:

    To further verify that R is working properly, you can try typing some basic R commands in the console. For example, you can type “2 + 2” and press Enter. R should return the result, which is 4.

If you are able to launch the R console and run basic commands successfully, it means that R is properly installed and you can start using it for data analysis and visualization.

Additional Packages: Install additional packages using “install.packages()”.

R has a comprehensive collection of packages that provide additional functionality for data analysis, visualization, and modeling. These packages can be installed using the “install.packages()” function.

To install a package, open the R console and type the following command:

“`
install.packages(“package_name”)
“`

Replace “package_name” with the name of the package you want to install. For example, to install the “ggplot2” package for data visualization, you would type:

“`
install.packages(“ggplot2”)
“`

Press Enter to execute the command. R will download and install the specified package along with its dependencies. Once the installation is complete, you can load the package into your R session using the “library()” function:

“`
library(package_name)
“`

Again, replace “package_name” with the name of the package you want to load. For example, to load the “ggplot2” package, you would type:

“`
library(ggplot2)
“`

You can now use the functions and datasets provided by the installed package in your R scripts and analyses.

Online Resources: Refer to R documentation and tutorials for further learning.

Once you have R installed and basic packages loaded, you can start learning how to use R for data analysis and visualization. There are numerous online resources available to help you get started and deepen your understanding of R.

  • R Documentation:

    The official R documentation is a comprehensive resource for learning about R’s functions, packages, and usage. It is available online and can be accessed from within the R console using the “help()” function. For example, to get help on the “ggplot()” function, you would type “help(ggplot)”.

  • R Tutorials:

    There are many free and paid R tutorials available online. These tutorials provide step-by-step instructions on how to use R for various tasks, such as data cleaning, visualization, and statistical modeling. Some popular R tutorial websites include RStudio’s “R for Beginners” tutorial, DataCamp, and Coursera.

  • R Forums and Communities:

    There are several online forums and communities where you can ask questions, share your work, and learn from other R users. Some popular R forums include the RStudio Community Forum, the R subreddit, and the R-help mailing list.

  • R Books:

    There are also many excellent books available that can help you learn R. Some popular R books include “R for Data Science” by Hadley Wickham, “The R Book” by Michael Friendly and Julian Simon, and “ggplot2: Elegant Graphics for Data Analysis” by Hadley Wickham.

Byを活用 these online resources, you can quickly ramp up your R skills and start using R to solve real-world problems.
