Shiny applications are made up of 2 important components: the user interface (UI) and the server section. In this section, we’ll take a closer look at the shiny application code you just ran. This will start the application and open up your default web browser so you view it. For now, try running the application on your computer by clicking the the “Run App” button in the RStudio IDE. We will go through each code chunk and explain what each one of them does in the next section.

# Run the application shinyApp( ui = ui, server = server)ĭon’t worry about how the application works exactly. # draw the histogram with the specified number of bins hist(x, breaks = bins, col = 'darkgray', border = 'white') # generate bins based on input$bins from ui.Rīins <- seq( min(x), max(x), length.out = input $bins + 1) # Define server logic required to draw a histogram # Show a plot of the generated distribution mainPanel( # Sidebar with a slider input for number of bins sidebarLayout( # Application title titlePanel( 'Old Faithful Geyser Data'), # Define UI for application that draws a histogram You can run the application by clicking # the 'Run App' button in the RStudio IDE or running the command runApp('app.R'). It will look something like this: # This is a Shiny web application. You can use this simple shiny application as a starting point for building your own applications. This will create the R script file app.R which contains the basic components of a shiny application. To access this template, click on the new document icon in the top left corner of the IDE and select “Shiny Web App…”. The RStudio IDE contains a basic shiny application template you can use to create your first shiny application. You can download shiny from CRAN using the command install.packages('shiny'). To get started, make sure you have the shiny package installed on your system.
