The following steps may be used to install R on a Macintosh operating system. See these directions for installing R on a Windows operating system.

Remember, the MacOS Mojave Installer application deletes itself automatically after macOS Mojave has successfully installed, thus even if you previously downloaded the installer and used it to install Mojave on the same Mac, unless you previously had made a copy of it then it will have removed itself, thus you’d need to re-download it again. The instructions offered here describe both the process for installing and the process for reinstalling OS X. Here’s how to install (or reinstall) OS X, step by step: Boot from your Recovery HD partition by restarting your Mac while holding down the cmd+R keys. The OS X Utilities window appears. Select Reinstall OS X, and click Continue.

1. Go to the RStudio Comprehensive R Archive Network (CRAN) mirror at https://cran.rstudio.com. [You can select a different mirror by going to http://www.r-project.org, selecting the “download R” link in the “Getting Started” box, and selecting a mirror location from the ensuing page.]

2. Select the “Download R for (Mac) OS X” link.

3. Select the “R-3.2.2.pkg” option (or similar if the version number has changed … the version is now at least 3.4.3) if running Mac OS 10.9 (Mavericks) and higher. (note that the binary support for OS X before Mavericks is deprecated.)

4. Locate the downloaded package on your computer (called “R-3.2.2.pkg” or similar if the version number has changed) and run it.

5. Select Continue in the first three dialog boxes (first, an installer description; second, a simple software description; third, a user agreement).

6. Select Agree to accept the terms of the software license agreement.

   Acrobat Reader DC is everyone’s top choice for a PDF reader. The additional tools are, without a doubt, very useful and make the software even more flexible. With its ability to upload files in cloud storage, secure PDFs with passwords, and being available for use in mobile devices, Acrobat Reader is definitely a must-have tool.

7. Select to install R for all users or on a specific disk (simply use the all users option unless you wish to install R on a disk partition or external drive). Press Continue. (Note that you must select an option before the Continue button will activate.)

8. Select Install.

9. A dialog box will prompt you for the password to your user account. Calculator for macbook pro free download. Input your password and press Install Software.

10. R should then begin installing files. If everything goes well, then you should get one last dialog box noting such. Press Close.

If you plan to use RStudio, then you can now install it with these directions.
