Whenever I try to run an application that has interactivity (for example, the input signal is close in the course notes), I get an output similar to the one below. I get a listen on http: // ... right after entering runApp (). I get an error as soon as the URL page opens. I tried uninstalling and reinstalling both shiny and rtools. The only difference that I saw as a result of my actions is that when you start the application, where before opening the browser in Chrome, this application opens the R window, which immediately closes.

ui.R
library(shiny) shinyUI(pageWithSidebar( headerPanel("Illustrating inputs"), sidebarPanel( numericInput('id1', 'Numeric input, labeled id1', 0, min = 0, max = 10, step = 1), checkboxGroupInput("id2", "Checkbox", c("Value 1" = "1", "Value 2" = "2", "Value 3" = "3")), dateInput("date", "Date:") ), mainPanel( h3('Illustrating outputs'), h4('You entered'), verbatimTextOutput("oid1"), h4('You entered'), verbatimTextOutput("oid2"), h4('You entered'), verbatimTextOutput("odate") ) ))
server.R
library(shiny) shinyServer( function(input, output) { output$oid1 <- renderPrint({input$id1}) output$oid2 <- renderPrint({input$id2}) output$odate <- renderPrint({input$date}) } )
I use Windows 7 and Google Chrome as my browser.
