Shiny file upload demo

server.R

shinyServer(function(input, output) {
  output$filetable <- reactiveTable(function() {
    if (is.null(input$files)) {
      # User has not uploaded a file yet
      return(NULL)
    }
    
    input$files
  })
})

ui.R

shinyUI(pageWithSidebar(
  headerPanel("File input test"),
  sidebarPanel(
    fileInput("files", "File data", multiple=TRUE)
  ),
  mainPanel(
    tableOutput("filetable")
  )
))

I'm running my app locally and can't seem to do a multi-select for files when I specify "multiple=TRUE". I'm on Mac OS Yosemite. If it's local, don't see how my web browser figures into this. Has anyone else had this problem? I tried shift-clicking, command-clicking, command-A, and nothing works.

What about if i don't wanna return all the file informations but just the filename. Like for example '/User/Documents/.../filename' the output would look like 'filename'
