R-Commander is a an easy to use Graphical User Interface to run statistical applications using the R statistical engine. Much of what you can do in native command line R can be done easily in R-Commander without knowing any of the command line features in R. This reduces the time considerably it takes to perform analyses
Command + R Not Working. Before starting the troubleshooting process to force Mac into the recovery mode, make sure there is no firmware password in place, if so, then remove the password as you will not be able to use the recovery options if the firmware password is in place. Moreover, the recovery options are only available to the Lion macOS or above, so, make sure. How to Install R and the ‘R Commander’ The ‘R Commander’ is a basic-statistics graphical user interface (GUI) for R, a free interactive programming language and environment. Therefore, in order to be able to use the R Commander, you must install both R and the R Commander.
Before you get started, make sure you have downloaded the Chrome browser and set that as your default. (http://chrome.google.com ) Safari is quirky and while it may work, it very well may not.
R programs and algorithms are distributed by the Comprehensive R Archive Network. A simple graphic user interface is included for Mac users; R Commander can be installed using the built-in package installer, which can also install file import features (which aren't installed by default). R Commander is an X11 program, which means it uses an.
Installing XQuartz
The process for installing R-Commander on your Mac is pretty straightforward. If you are using MacOS 10.11 or higher you will first need to install XQuartz. XQuartz is the environment that R and R-Commander reside in on the Mac. If your OS is older than 10.11 you may already have XQuartz installed as part of the MacOS (but frankly you shouldn’t be running an OS that old). Go here:
After the package has downloaded, it will be in the lower left corner of your browser frame, you may click on it there or find it and click on it.
Just accept the defaults.
Agree to the license terms.
Then click “Install”.
Like all mac apps you will have to put in your MAC username and password. That is probably DIFFERENT than your VUNetID and ePassword.
It will take a while for the scripts to run and complete the install. Be patient; that “less than a minute” comment is not very serious.
You will be notified that the installation was successful.

Once you are told that, you will not need to install this again on this computer. You may be asked if you want to delete the installer pkg file. You may do so if you need the space. That will have no impact on the installed application, XQuartz.
Installing R
After successfully installing XQuartz, you will now go here and install R: (copy the URL below and paste into Chrome)
Click the download “R for (Mac) OS X”
Click the .pkg file circled below to download the file. The link to it will be placed in the lower left of your browser frame.
Click on the downloaded file in the lower left of the browser frame (in Chrome) and start the installation process. Just accept the defaults.
Click Continue
Click Continue
Agree to the license agreement.
Run the Install.
Again, put in your Apple username and password and click “Install Software”.
It will take a while to run the scripts so be patient. That one minute comment below is not to be taken very seriously.
You will be notified when the installation is successful. Click “Close”.
Installing R-Commander
Now we will launch R and from within R will install R-Commander. Go to your applications folder and Find R. The icon looks like this:
Notice the caret prompt that looks like a greater than sign. “>”
At the prompt, type in (with NO spaces and all in lower case) install.packages()
Mac keyboard light up. You may copy/paste it from here.
You will now be asked to select a mirror site to download the package from.
Click in the window and scroll down (it helps if you have a mouse as opposed to the computer’s trackpad) to USA (CA 1) [https]. This is the Berkeley site and is generally the most current.
Now you will be given a list of packages you can install. There are literally hundreds of them. Scrolling here again works much better with an actual computer mouse.
Look for Rcmdr. There will be a number of Rcmdr plug-ins that follow but you are only interested in the first one. Select it and click “OK”.
You will see a lot downloaded the first time. It may take considerable time for this process to complete. When it is done you will see the caret prompt.
R-Commander has been downloaded and installed. You may be prompted to install additional packages that may not have come down in the most recent package. Go ahead and do that if asked.
Starting R-Commander
At the prompt type in: library(Rcmdr) with no spaces. You may copy/paste from here. You will do this EVERY TIME you launch the application. The first time though, it may tell you that you need to download some required packages. Accept the defaults and download those packages. After those packages are downloaded and installed the first time, you will not be asked again to do so.
To launch R-Commander, first click on R in your applications menu, then from the caret prompt type in library(Rcmdr)
You're both replying to a post that is one year old, for older verson of Safari.Regarding 'i s it possible to 'downgrade' to an older or previous version of Safari?' That's a question for Apple, not Flash Player forums.Apple dropped support for Flash Player in Safari 14 ahead of Flash Player's end-of-life at the end of 2020. Adobe flash plug in for mac.
Safe ip for mac. When you see this screen you are ready to run your statistics.
This concludes the installation of R-Commander. You will only have to repeat this process if you want to install all of this on a different computer.

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 to work with R, RStudio makes life a lot easier.
Download R from the Comprehensive R Archive Network (CRAN). In your browser, type this address if you work in Windows:
cran.r-project.org/bin/windows/base/
Type this one if you work on the Mac:
cran.r-project.org/bin/macosx/
Click the link to download R. This puts the win.exe file in your Windows computer, or the .pkg file in your Mac. In either case, follow the usual installation procedures. When installation is complete, Windows users see an R icon on their desktop, Mac users see it in their Application folder.
Both URLs provides helpful links to FAQs. The Windows-related URL also links to “Installation and other instructions.”
Now for RStudio.
Click the link for the installer for your computer, and again follow the usual installation procedures.

After the RStudio installation is finished, click the RStudio icon to open the window shown.
Download R For Mac
If you already have an older version of RStudio and you go through this installation procedure, the install updates to the latest version (and you don’t have to uninstall the older version).
The large Console pane on the left runs R code. One way to run R code is to type it directly into the Console pane.
The other two panes provide helpful information as you work with R. The Environment and History pane is in the upper right. The Environment tab keeps track of the things you create (which R calls objects) as you work with R. The History tab tracks R code that you enter.
Get used to the word object. Everything in R is an object.
The Files, Plots, Packages, and Help tabs are in the pane in the lower right. The Files tab shows files you create. The Plots tab holds graphs you create from your data. The Packages tab shows add-ons (called packages) you downloaded as part of the R installation. Bear in mind that “downloaded” doesn’t mean “ready to use.” To use a package’s capabilities, one more step is necessary, and you’ll want to use packages.
This figure shows the Packages tab. The packages are in either the user library (which you can see in the figure) or the system library (which you have to scroll down to).
The Help tab, shown here, provides links to a wealth of information about R and RStudio.

To tap into the full power of RStudio as an IDE, click the larger of the two icons in the upper right corner of the Console pane. That changes the appearance of RStudio so that it looks like this:
The top of the Console pane relocates to the lower left. The new pane in the upper left is the Scripts pane. You type and edit code in the Scripts pane and press Ctrl+R (Command+Enter on the Mac), and then the code executes in the Console pane.
Ctrl+Enter works just like Ctrl+R. You can also select
Code → Run Selected Line(s)
