闪亮的输出取决于浏览器

Question

My shiny app is not working well on internet explorer and I want the app does not appear for this browser.

Do you know any R fuction that I can discover the browser??

Example:

if( browser = IE){    
    "use Mozilla, chrome or safari"}    
else{
    run my app}

Thanks!

session$request contains a HTTP_USER_AGENT value if one is given. You could probably use that to work out what browser is being used:

library(shiny)
runApp(list(
  ui = bootstrapPage(
    textOutput("text")
  ),
  server = function(input, output, session) {
    myReactives <- reactiveValues(ua = session$request$HTTP_USER_AGENT)
    output$text <- renderText({
      myReactives$ua
    })
  }
))
