Examples

if (FALSE) { # interactive()
library(shiny)

ui <- fluidPage(
   sidebarLayout(
     sidebarPanel(
       # Create a filterInput() inside a shiny app:
       filterInput(
        x = letters,
        inputId = "letter",
        label = "Pick a letter:"
       )
     ),
     mainPanel(
       textOutput("selected_letter")
     )
   )
)

server <- function(input, output, session) {
   output$selected_letter <- renderText({
     paste("You selected:", input$letter)
   })
}

shinyApp(ui, server)
