Integration with R Shiny

This tutorial will help you integrate Flexmonster with the R Shiny application. It is based on How to build a Shiny app guide.

Prerequisites

To run a simple application, you will need R. Get it here if it’s not already installed on your machine.

Then open the R console and install the Shiny package by running:

 install.packages("shiny") 

After that, choose one of the following options:

  1. Integrate Flexmonster into an existing/new application
  2. Run a simple R Shiny and Flexmonster sample from GitHub

Integrate Flexmonster into an existing/new application

To integrate Flexmonster into an R Shiny app, follow these steps:

Step 1. If you don’t have an R Shiny app, create a new empty folder (e.g. shinyapp/) with an empty app.r file within it.

Step 2. In the app.r file, include Shiny to your application:

library(shiny)

Step 3. In the app.r file, define a simple server implementation:

server <- function(input, output) {

}

Step 4. In an .html file (e.g. index.html), create a <div> container for the component:

<div id="pivotContainer">The component will appear here</div>

Step 5. Include flexmonster.js in your HTML page:

<div id="pivotContainer">The component will appear here</div>
<script src="https://cdn.flexmonster.com/flexmonster.js"></script>

Step 6. Add a simple script to embed the component. Note that licenseKey is your license or trial key, so replace XXXX-XXXX-XXXX-XXXX-XXXX with an actual key. If you don’t have a license key, get a trial key here.

<div id="pivotContainer">The component will appear here</div>
<script src="https://cdn.flexmonster.com/flexmonster.js"></script>
<script>
var pivot = new Flexmonster({
container: "pivotContainer",
componentFolder: "https://cdn.flexmonster.com/",
toolbar: true,
licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});
</script>

Step 7. Configure a simple report:

 <div id="pivotContainer">The component will appear here</div>
<script src="https://cdn.flexmonster.com/flexmonster.js"></script>

<script type="text/javascript">
var pivot = new Flexmonster({
container: "pivotContainer",
componentFolder: "https://cdn.flexmonster.com/",
toolbar: true,
report: {
dataSource: {
type: "JSON",
filename: "https://cdn.flexmonster.com/data/data.json"
}
},

licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});
</script>

Step 8. In the app.r file, define the user interface by calling the htmlTemplate function with the HTML file (e.g. index.html) as a parameter.

ui <- htmlTemplate("index.html")

Step 9. Add the shinyApp function that uses the ui object and the server function to build a Shiny app object:

shinyApp(ui, server)

Step 10. Run your application from the R console:

library(shiny)
runApp('~/shinyapp')

The application will be automatically opened in your browser.

It can be shut down manually with Ctrl+C.

If any errors appear on this step, refer to the troubleshooting subsection.

Run a simple R Shiny and Flexmonster sample from GitHub

Step 1. Download the .zip archive with the sample or clone it from GitHub with the following command:

git clone https://github.com/flexmonster/pivot-r-shiny my-proj
cd my-proj

Step 2. Open the www/index.html file and add your license or trial key to the Flexmonster object. If you don’t have a license key, get a trial key here.

var pivot = new Flexmonster({
componentFolder: "https://cdn.flexmonster.com/",
container: "pivotContainer",
toolbar: true,
report: {
dataSource: {
data: jsonData
}
},
licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});

Step 3. Run your application from the R console:

library(shiny)
runApp('~/my-proj')

The application will be automatically opened in your browser.

It can be shut down manually with Ctrl+C.

If any errors appear on this step, refer to the troubleshooting subsection.

Troubleshooting

While completing this tutorial, users may face problems with running the app, especially users working with macOS or Linux operating systems. This subsection provides simple instructions on how to fix errors that may be encountered.

Error: No Shiny application exists at the path

If you followed the tutorial accurately and got such an error, one of the instructions below may help fix it:

  • Make sure the right path to the project folder was specified when running the app. Note that if the app is run right in the project folder (e.g., my-proj/), the runApp() function should be called without parameters:
    library(shiny)
    runApp()

Note that the following instructions apply only to UNIX-like systems (macOS, Linux, and so forth):

  • Try starting the R’s interactive shell without superuser privileges. It can be done with the following command:
    R
    Then run the app with commands from the guide:
    library(shiny)
    runApp('~/my-proj')
  • Running the app right from the terminal may also help. To do this, open the terminal in the project folder (e.g., my-proj/) and run the following command:
    R -e "shiny::runApp()"
  • The following command can also be used to run the app from the terminal opened in the project folder:
    Rscript app.R
