sidebarLayout function

Layout a sidebar and main area

Create a layout (sidebarLayout()) with a sidebar (sidebarPanel()) and main area (mainPanel()). The sidebar is displayed with a distinct background color and typically contains input controls. The main area occupies 2/3 of the horizontal width and typically contains outputs.

sidebarLayout(
  sidebarPanel,
  mainPanel,
  position = c("left", "right"),
  fluid = TRUE
)

sidebarPanel(..., width = 4)

mainPanel(..., width = 8)

Arguments

• sidebarPanel: The sidebarPanel() containing input controls.
• mainPanel: The mainPanel() containing outputs.
• position: The position of the sidebar relative to the main area ("left" or "right").
• fluid: TRUE to use fluid layout; FALSE to use fixed layout.
• ...: Output elements to include in the sidebar/main panel.
• width: The width of the sidebar and main panel. By default, the sidebar takes up 1/3 of the width, and the main panel 2/3. The total width must be 12 or less.

Examples

## Only run examples in interactive R sessions
if (interactive()) {
options(device.ask.default = FALSE)

# Define UI
ui <- fluidPage(

  # Application title
  titlePanel("Hello Shiny!"),

  sidebarLayout(

    # Sidebar with a slider input
    sidebarPanel(
      sliderInput("obs",
                  "Number of observations:",
                  min = 0,
                  max = 1000,
                  value = 500)
    ),

    # Show a plot of the generated distribution
    mainPanel(
      plotOutput("distPlot")
    )
  )
)

# Server logic
server <- function(input, output) {
  output$distPlot <- renderPlot({
    hist(rnorm(input$obs))
  })
}

# Complete app with UI and server components
shinyApp(ui, server)
}
