Data Menu for Radiant: Business Analytics using R and Shiny

The Radiant Data menu includes interfaces for loading, saving, viewing, visualizing, summarizing, transforming, and combining data. It also contains functionality to generate reproducible reports of the analyses conducted in the application.

CRAN_Status_Badge

Radiant is an open-source platform-independent browser-based interface for business analytics in R. The application is based on the Shiny package and can be run locally or on a server. Radiant was developed by Vincent Nijs. Please use the issue tracker on GitHub to suggest enhancements or report problems: https://github.com/radiant-rstats/radiant.data/issues. For other questions and comments please use [email protected].

Key features

  • Explore: Quickly and easily summarize, visualize, and analyze your data
  • Cross-platform: It runs in a browser on Windows, Mac, and Linux
  • Reproducible: Recreate results and share work with others as a state file or an Rmarkdown report
  • Programming: Integrate Radiant's analysis functions with your own R-code
  • Context: Data and examples focus on business applications

Explore

Radiant is interactive. Results update immediately when inputs are changed (i.e., no separate dialog boxes) and/or when a button is pressed (e.g., Estimate in Model > Estimate > Logistic regression (GLM)). This facilitates rapid exploration and understanding of the data.

Cross-platform

Radiant works on Windows, Mac, or Linux. It can run without an Internet connection and no data will leave your computer. You can also run the app as a web application on a server.

Reproducible

To conduct high-quality analysis, simply saving output is not enough. You need the ability to reproduce results for the same data and/or when new data become available. Moreover, others may want to review your analysis and results. Save and load the state of the application to continue your work at a later time or on another computer. Share state files with others and create reproducible reports using Rmarkdown. See also the section on Saving and loading state below

If you are using Radiant on a server you can even share the URL (include the SSUID) with others so they can see what you are working on. Thanks for this feature go to Joe Cheng.

Programming

Although Radiant's web-interface can handle quite a few data and analysis tasks, you may prefer to write your own R-code. Radiant provides a bridge to programming in R(studio) by exporting the functions used for analysis (i.e., you can conduct your analysis using the Radiant web-interface or by calling Radiant's functions directly from R-code). For more information about programming with Radiant see the programming page on the documentation site.

Context

Radiant focuses on business data and decisions. It offers tools, examples, and documentation relevant for that context, effectively reducing the business analytics learning curve.

How to install Radiant

  • Required: R version 3.4.0 or later
  • Required: Rstudio version 1.1.453 or later

In Rstudio you can start and update Radiant through the Addins menu at the top of the screen. To install the latest version of Radiant for Windows or Mac, with complete documentation for off-line access, open R(studio) and copy-and-paste the command below:

install.packages("radiant", repos = "https://radiant-rstats.github.io/minicran/")

Once all packages are installed, select Start radiant from the Addins menu in Rstudio or use the command below to launch the app:

radiant::radiant()

To launch Radiant in Rstudio's viewer pane use the command below:

radiant::radiant_viewer()

To launch Radiant in an Rstudio Window use the command below:

radiant::radiant_window()

To easily update Radiant and the required packages, install the radiant.update package using:

install.packages("radiant.update", repos = "https://radiant-rstats.github.io/minicran/")

Then select Update radiant from the Addins menu in Rstudio or use the command below:

radiant.update::radiant.update()

See the installing radiant page additional for details.

Optional: You can also create a launcher on your Desktop to start Radiant by typing radiant::launcher() in the R(studio) console and pressing return. A file called radiant.bat (windows) or radiant.command (mac) will be created that you can double-click to start Radiant in your default browser. The launcher command will also create a file called update_radiant.bat (windows) or update_radiant.command (mac) that you can double-click to update Radiant to the latest release.

When Radiant starts you will see data on diamond prices. To close the application click the icon in the navigation bar and then click Stop. The Radiant process will stop and the browser window will close (Chrome) or gray-out.

Documentation

Documentation and tutorials are available at https://radiant-rstats.github.io/docs/ and in the Radiant web interface (the icons on each page and the icon in the navigation bar).

Individual Radiant packages also each have their own pkgdown sites:

Want some help getting started? Watch the tutorials on the documentation site.

Reporting issues

Please use the GitHub issue tracker at github.com/radiant-rstats/radiant/issues if you have any problems using Radiant.

Try Radiant online

Not ready to install Radiant on your computer? Try it online at the link below:

https://vnijs.shinyapps.io/radiant

Do not upload sensitive data to this public server. The size of data upload has been restricted to 10MB for security reasons.

Running Radiant on shinyapps.io

To run your own instance of Radiant on shinyapps.io first install Radiant and its dependencies. Then clone the radiant repo and ensure you have the latest version of the Radiant packages installed by running radiant/inst/app/for.shinyapps.io.R. Finally, open radiant/inst/app/ui.R and deploy the application.

Running Radiant on shiny-server

You can also host Radiant using shiny-server. First, install radiant on the server using the command below:

install.packages("radiant", repos = "https://radiant-rstats.github.io/minicran/")

Then clone the radiant repo and point shiny-server to the inst/app/ directory. As a courtesy, please let me know if you intend to use Radiant on a server.

When running Radiant on a server, by default, file uploads are limited to 10MB and R-code in Report > Rmd and Report > R will not be evaluated for security reasons. If you have sudo access to the server and have appropriate security in place you can change these settings by adding the following lines to .Rprofile for the shiny user on the server.

options(radiant.maxRequestSize = -1)  ## no file size limit 
options(radiant.report = TRUE)

Running Radiant in the cloud (e.g., AWS)

To run radiant in the cloud you can use the customized Docker container. See https://github.com/radiant-rstats/docker for details

Saving and loading state

To save your analyses save the state of the app to a file by clicking on the icon in the navbar and then on Save radiant state file (see also the Data > Manage tab). You can open this state file at a later time or on another computer to continue where you left off. You can also share the file with others that may want to replicate your analyses. As an example, load the state file radiant-example.state.rda by clicking on the icon in the navbar and then on Load radiant state file. Go to Data > View and Data > Visualize to see some of the settings from the previous "state" of the app. There is also a report in Report > Rmd that was created using the Radiant interface. The html file radiant-example.nb.html contains the output.

A related feature in Radiant is that state is maintained if you accidentally navigate to another web page, close (and reopen) the browser, and/or hit refresh. Use Refresh in the menu in the navigation bar to return to a clean/new state.

Loading and saving state also works with Rstudio. If you start Radiant from Rstudio and use > Stop to stop the app, lists called r_data, r_info, and r_state will be put into Rstudio's global workspace. If you start radiant again using radiant::radiant() it will use these lists to restore state. Also, if you load a state file directly into Rstudio it will be used when you start Radiant to recreate a previous state.

Technical note: Loading state works as follows in Radiant: When an input is initialized in a Shiny app you set a default value in the call to, for example, numericInput. In Radiant, when a state file has been loaded and an input is initialized it looks to see if there is a value for an input of that name in a list called r_state. If there is, this value is used. The r_state list is created when saving state using reactiveValuesToList(input). An example of a call to numericInput is given below where the state_init function from radiant.R is used to check if a value from r_state can be used.

numericInput("sm_comp_value", "Comparison value:", state_init("sm_comp_value", 0))

Source code

The source code for the radiant application is available on GitHub at https://github.com/radiant-rstats. radiant.data, offers tools to load, save, view, visualize, summarize, combine, and transform data. radiant.design builds on radiant.data and adds tools for experimental design, sampling, and sample size calculation. radiant.basics covers the basics of statistical analysis (e.g., comparing means and proportions, cross-tabs, correlation, etc.) and includes a probability calculator. radiant.model covers model estimation (e.g., logistic regression and neural networks), model evaluation (e.g., gains chart, profit curve, confusion matrix, etc.), and decision tools (e.g., decision analysis and simulation). Finally, radiant.multivariate includes tools to generate brand maps and conduct cluster, factor, and conjoint analysis.

These tools are used in the Business Analytics, Quantitative Analysis, Research for Marketing Decisions, Consumer Behavior, Experiments in Firms, Pricing, and Customer Analytics classes at the Rady School of Management (UCSD).
