How to Install and Use R on Your iPhone for Statistical Computing and Graphics
How to Download and Use R on Your iPhone
R is a programming language that can help you perform statistical computing and graphics with your data. It is widely used by data scientists, statisticians, researchers, and educators for data analysis and visualization. However, if you want to use R on your iPhone, you may encounter some challenges and limitations, as iOS devices do not support R natively. In this article, I will show you two ways to run R code and display graphs on your iPhone: using a third-party app called R Programming Compiler, or using a web-based service such as RStudio Server or Jupyter Hub.

How to use R Programming Compiler app
R Programming Compiler is an app that allows you to write and run R code directly on your iPhone, iPad, or iPod Touch. It is ideal for learning and testing code snippets, as well as plotting and graphing data. Here is how you can use it:
Download and install the app from the App Store. It is free to download, but it offers in-app purchases for premium features such as unlimited plots, package installation, and latest compilers.
Open the app and tap on the + button at the top right corner to create a new file. You can also tap on the Open button at the bottom left corner to open an existing file from your device or iCloud.
Type or paste your R code in the editor. You can use the custom keyboard for easy input of frequently used characters, such as parentheses, brackets, quotes, etc. You can also select and run a chunk of code by tapping on it.
Tap on the Run button at the bottom right corner to compile and run your code. You will see the output or error in the Output tab below. You can also view plots or graphs in the Plot tab if your code generates any.
To save your file, tap on the Save button at the top left corner. You can choose a name and location for your file. You can also import or share your file via email, AirDrop, Dropbox, etc.
Some of the features and benefits of using this app are:
It supports different R compiler versions, namely: 4.0.x and 4.1.x.
It supports plotting and graphing with various graphics devices such as pdf, png, jpeg, etc.
It has a language reference that provides examples of common. How to use RStudio Server or Jupyter Hub web services
Another way to run R on your iPhone is to use a web-based service that provides an online environment for R programming. Two popular options are RStudio Server and Jupyter Hub, which are both open-source and can be deployed on your own server or cloud provider. Here is how you can use them:
Set up and access an RStudio Server or Jupyter Hub account online. You will need to have access to a server that runs Linux and has R installed. You can follow the instructions on the official websites of [RStudio Server](^1^) or [Jupyter Hub](^6^) to install and configure them. Alternatively, you can use a cloud service that offers pre-configured instances of RStudio Server or Jupyter Hub, such as [Posit](^4^), [SCINet](^5^), or [Binder](^12^).
Use a web browser or Juno app to connect to the server or hub. You can use any web browser on your iPhone, such as Safari or Chrome, to access the web interface of RStudio Server or Jupyter Hub. You will need to enter the URL of your server or hub, and log in with your username and password. Alternatively, you can use Juno app, which is a specialized browser for iOS devices that supports RStudio Server and Jupyter Hub. Juno app also provides some extra features, such as keyboard shortcuts, code completion, and file management.
Write and run R code and view the output or error in the web interface. You will see a familiar interface of RStudio IDE or Jupyter Notebook, where you can write and execute R code in an interactive way. You can also view the output or error of your code in the console or notebook cells. You can also use various tools and features provided by RStudio IDE or Jupyter Notebook, such as debugging, testing, version control, etc.
Plot and graph data using the web interface. You can also create plots and graphs with your data using the web interface of RStudio Server or Jupyter Hub. You can use the built-in graphics devices of R, such as plot, ggplot2, lattice, etc., or install additional packages for more advanced visualization. You can view the plots and graphs in the Plots pane of RStudio IDE or the notebook cells of Jupyter Notebook.
Open, save, import and share R files using the web interface. You can also manage your R files using the web interface of RStudio Server or Jupyter Hub. You can open, save, import and share your files using the Files pane of RStudio IDE or the File menu of Jupyter Notebook. You can also upload or download files from your device or cloud storage using the Upload or Download buttons.
Some of the features and benefits of using these web services are:
They provide a full-featured and familiar environment for R programming, with all the tools and functions that you need.
They allow you to access your R projects from anywhere and any device, as long as you have an internet connection.
They enable you to collaborate with others on your R projects, by sharing your files or notebooks online.
They support different versions of R and various packages and libraries for R.
Some of the drawbacks and limitations of using these web services are:
They require an internet connection and a server to run, which may incur some costs and maintenance issues.
They may have some performance issues or lag depending on your network speed and server load.
They may not support some features or functions that are specific to your device or platform.
Conclusion
In this article, I have shown you how to download and use R on your iPhone using two methods: using a third-party app called R Programming Compiler, or using a web-based service such as RStudio Server or Jupyter Hub. Both methods have their advantages and disadvantages, depending on your needs and preferences. Here is a summary of their main differences:
R Programming Compiler appRStudio Server/Jupyter Hub web services
InstallationEasy to download and install from the App StoreRequires access to a server that runs Linux and has R installed
ConnectionWorks offline without internet connectionRequires internet connection to access the server
InterfaceSimplified editor for writing and running code snippetsFull- featured and familiar environment for R programming
FeaturesSupports different R compiler versions and plotting devicesSupports different R versions and packages, as well as various tools and functions
BenefitsIdeal for learning and testing code snippets, as well as plotting and graphing dataIdeal for working on complex and collaborative R projects, with all the tools and functions that you need
DrawbacksLimited by the device memory and storage, and does not support package installation or latest compilersDependent on the network speed and server load, and may not support some device-specific features or functions
Based on this comparison, you can choose the best method for your needs. If you are looking for a simple and convenient way to write and run R code snippets, as well as plot and graph data, on your iPhone, you may prefer the R Programming Compiler app. If you are looking for a full-featured and familiar way to work on complex and collaborative R projects, with all the tools and functions that you need, on your iPhone, you may prefer the RStudio Server or Jupyter Hub web services. Of course, you can also use both methods depending on the situation.
