        )
      )
    ),
  server =
    function(input, output, session) {

      randomVals <- eventReactive(input$go, {
        runif(input$n)
      })

      plotInput <- function(){hist(randomVals())}

      output$plot <- renderPlot({
        hist(randomVals())
      })

      output$downloadPlot <- downloadHandler(
        filename = "Shinyplot.png",
        content = function(file) {
          png(file)
          plotInput()
          dev.off()
        }) 

    }
)
