However there are three bugs in the code provided below. It also follows good practice and makes use of reactive expressions to avoid redundancy of code.

The following app is very similar to one you’ve seen earlier in the chapter: you select a dataset from a package (this time we’re using the ggplot2 package) and the app prints out a summary and plot of the data. Server <- function ( input, output, session ) shinyApp ( ui, server ) We only see the input, not the two outputs, because we haven’t yet told Shiny how the input and outputs are related. You’ll now see Figure 1.3, a page containing a select box. Layout functions, inputs, and outputs have different uses, but they are fundamentally the same under the covers: they’re all just fancy ways to generate HTML, and if you call any of them outside of a Shiny app, you’ll see HTML printed out at the console.ĭon’t be afraid to poke around to see how these various layouts and controls work under the hood. You’ll learn more about outputs in Section 2.3. VerbatimTextOutput() displays code and tableOutput() displays tables. VerbatimTextOutput() and tableOutput() are output controls that tell Shiny where to put rendered output (we’ll get into the how in a moment). You’ll learn more about inputs in Section 2.2. In this case, it’s a select box with the label “Dataset” and lets you choose one of the built-in datasets that come with R. SelectInput() is an input control that lets the user interact with the app by providing a value. You’ll learn more about them in Section 6.2. Ui <- fluidPage ( selectInput ( "dataset", label = "Dataset", choices = ls ( "package:datasets" ) ), verbatimTextOutput ( "summary" ), tableOutput ( "table" ) )įluidPage() is a layout function that sets up the basic visual structure of the page. I’ll cover other workflow patterns in Chapter 5. If you’re using RStudio, you don’t even need to stop and re-start the app to see your changes - you can either press the Reload app button in the toolbox or use the Cmd/Ctrl + Shift + Enter keyboard shortcut. The basic workflow of Shiny app development is to write some code, start the app, play with the app, write some more code, and repeat. You can stop the app and return access to the console using any one of these options:Ĭlick the stop sign icon on the R console toolbar.Ĭlick on the console, then press Esc (or press Ctrl + C if you’re not using RStudio). This means that you can’t run new commands at the R console until the Shiny app stops. While a Shiny app is running, it “blocks” the R console. You can enter that URL into any compatible 2 web browser to open another copy of your app.Īlso notice that R is busy: the R prompt isn’t visible, and the console toolbar displays a stop sign icon. For the latest updates, please refer to the product page on tells you the URL where your app can be found: 127.0.0.1 is a standard address that means “this computer” and 3827 is a randomly assigned port number. In the event that page modifications and adjustments are necessary, no special notice will be given.
