Install R On A Mac


Installing R on your Mac step-by-step. The easiest way is to install R through the Comprehensive R Archive Network (CRAN). Note that CRAN doesn’t have Mac OS X systems and can’t check these binaries for viruses. So they recommend using standard security precautions. $ brew install R. Then verify that the R environment is installed and ready, by running in a Terminal, $ R. And within the R REPL, run demo(nlm) to verify whether it will show the demos and the graph. Install RStudio Desktop on macOS. After the R environment is ready, we can move to to install the RStudio Desktop. Double click on the downloaded R package (PKG file) in the folder you specified. An example is shown below. Follow the installation instructions. You do not need to open R after the completed installation. RStudio will automatically do that after it is installed and opened. Download RStudio.

R has been one of the popular languages for anything to do with large amount of data. There are loads of useful packages that let you get started immediately in using a wide realm of statistical/computational tools. Installing an R package is easy. Typically, R Packages can be downloaded as “tar.gz” file for Mac OS X from CRAN sources. The command to install a R package to all users in your machine is

Local Installation of R Packages

Sometimes you might want to install a R package locally, either because you may not have root access to install a package globally or you may just want to try out a new package before installing globally. Here is how to install a R package locally from the terminal.

To install a R package locally, specify the local directory where you want to install by using the “-l” option in the “R CMD INSTALL” command. For example, to install the R package in the local directory “/usr/me/localR/library”, use the “R CMD INSTALL” as follows.

How to Load a Locally Installed R Package and Use it?

Installing R Packages at a local directory is only a first step. There are a few ways to load the locally installed R packages and use them. One option is to specify the local path to the R package while loading the library. The R command to load a general package is

To load a locally installed R package, use the library command with parameter lib.loc as

Another option is to instruct your .bashrc file to add the the path to local R library. This option lets you load the package without specifying the local every time. To enable this add the following to your .bashrc

After adding you can check if the local R package directory in the R library path using the R command “.libPaths()“. Typing “.libPaths()” in R, will show all the R library paths. If your local R library path is not added properly, you will only see one general path to R library, like “/opt/R/2.11.1/lib64/R/library”.

Install Guide

Mac Os X Installer

The definitive guide to installing rattle on the Mac as of June2018 comes via Zhiya Zuowhere Yihui Xie (RStudio) notedthat he has pre-built the binaries of RGtk2 and cairoDevice so that wecan easily install rattle. Thanks to Yihui. Note thathttps://macos.rbind.org has disappeared and has probably been replacedby https://macos.rbind.io.

Install R Mac Catalina

Asara Senaratne tested the following steps 2020-08-03:

Install r studio mac
  • You need to have macports installed. Select the correct one based on your OS from this https://www.macports.org/install.php and install it.
  • If you already have a terminal running, restart it and run the command: sudo port install gtk2 ## (X11 -- not aqua).
  • Then, run: export PATH=/opt/local/bin:/opt/local/sbin:$PATH
  • Run 'R' in the terminal to get the R command line and run: install.packages('RGtk2',type='source')
  • Next, run: install.packages('rattle',type='source')
  • Install: install.packages('rpart.plot') to get the plots
  • Restart R and try: library(rattle); rattle()

Eric Lin provided the following steps 2020-03-03. If asked toinstall by source say yes. If at any time during the process you areprompted for dependencies to be installed press yes. If you had afailed installation previously run brew doctor first to clearpotential problems. If there is a recommendation for a cleanup runbrew cleanup

  • Open up your Terminal.
  • You will need to install XCode Command Line Tools before installing R. We can install that by copy/pasting into terminal and pressing enter: xcode-select --install
  • Go to homebrew's website and copy/paste the command into terminal from here: https://brew.sh/
  • To install R, copy/paste this into your terminal and press enter: brew install r
  • We need some dependencies for Rattle: brew install gtk+
  • Ensure cairo does not exist yet (if you get an error that it doesn't exist that's fine): brew uninstall --force cairo --ignore-dependencies
  • Next: brew cask install xquartz
  • Next: brew install --with-x11 cairo
  • Now enter this command as capitalised: R
  • Copy and paste these commands one at a time within R and when asked for CRAN press 4 (ignore any warnings and note it may run for a while):
  • If asked to install dependencies or by source make sure to select yes.
  • This should install everything, including dependencies, successfully. If it does type the following to close R: q()
  • Enter back in: R
  • Load rattle library: library(rattle)
  • Load rattle: rattle()

    Other contributions are included for information. Thanks to everyonewho has contributed to getting Rattle running smoothly on the Mac.

    • Seb Kopf Jun 2014, Mac OS X 10.9.4, R 3.1.1, XQuartz, GTK 2.24

    Old Instructions

    Please ensure you have at least

    • Mac OS/X 10.12
    • XQuartz instead of X11
    • R 3.4.1 GUI 1.63 Snow Leopard build (6660)
    • GTK 2.24.17-X11
    • install.packages('rattle', repos='http://rattle.togaware.com', type='source”)

    Thanks to Rashid Zaman [140331] and Ivan Salgo [140603] forconfirming these requirements.Further information on installing the right version of GTK for Rversion 3 can be found on GitHub.Geoffrey Brown [150320] reports that for OSX 10.6.8, R 3.1.3 heinstalled XCode 3.2.6 and then install.packages('RGtk2',type='source') which worked for him.

    Quick Start

    • Install R
    • Startup R and then
    • > install.packages('RGtk2')
      > install.packages('rattle')
      > q()
    • Restart R and then
    • > library('rattle')
      > rattle()

    The rest of the required libraries get installed as you use Rattle.We install RGtk2 and the Gtk libraries separately as they can takesome time to download and install.

    The details are below.

    Dev Release

    The latest development version is available directly from Togaware:

    If you have issues with Rattle, then installing the latestdevelopment version is probably a good place to start.

    Details

    1. Install Latest R

    The first step is to install R

    • Download and install the latest version of R from CRAN, the Comprehensive R Archive Network. The link to R-latest.pkg will deliver the latest. Choosing all the defaults on the install works just fine.

    2. Install Rattle

    Then install Rattle using R's package manager. As a separate stepit is usually best to install the RGtk2 package which will downloadthe GTK libraries for Mac OS/X and link them into R. This can takesometime and is a prerequisite for loading Rattle.

    • Start R and enter the following command at the R prompt. R asks us to nominate a CRAN mirror. Choose a nearby location.

    • Restart R and then load Rattle with the following two commands at the R prompt. This loads the Rattle package into the library and starts up Rattle.

    Note on Installation of Rattle on Mountain Lion

    Thanks to Joe Trubisz for this script that he tested on severaldifferent machines and confirms it works (15 November 2013).

    1. Start R
    2. > install.packages('RGtk2', dependencies=TRUE)
    3. > install.packages('rattle', dependencies=TRUE)
      Wait ...
    4. Once done, q()
      If you have a 'unable to load' issue, then you most likely do not have the correct GTK+ library for Mountain Lion. If you have this issue, then kill X11 and R, go to ATT and download: GTK_2.24.17-X11.pkg and install it.
    5. Restart R
    6. > library(RGtk2)
      Once X11 starts, go to the task bar and select X11->Check forupdates. If there is an update, do the update, q() after theupdate and kill X11. If no update is present, skip to step 8.
    7. Redo steps 5 and 6 above
    8. demo(appWindow)
      Make sure that you can close the window successfully.
      If you are here, then you should be able to:
    9. > library(rattle)
    10. > rattle()
