title: How to place shiny panel near the pointer/mouse?
body: <p>I am building a shiny webapp in which I need to show plot points when hover over them. I managed to solve this by placing x, y , and other info of my array in a fixed draggable absolutepane. Is there a way to place this panel everytime the mouse hover over a point near the pointer ? Also, how can I hide the panel if the mouse isn't hovering any point ? 
  Currently, the panel is draggable and fixed at the top of the page using this code</p>
  
  <pre><code>ui &lt;- shinyUI(fluidPage(       
    absolutePanel(fixed=TRUE, draggable = TRUE,
                  verbatimTextOutput("hover_info")
    ),
    plotOutput("myplot",
               hover = hoverOpts(id ="myplot_hover")
    )
  ))
  
  server &lt;- shinyServer(function(input, output) {
  
    output$myplot &lt;- renderPlot({
      ggplot(mtcars) + geom_point(aes(mpg,cyl))
                              })
  
    output$hover_info &lt;- renderPrint({
      nearPoints(mtcars, input$myplot_hover,maxpoints=1)
                                    })
  })
  
  shinyApp(ui, server)
  </code></pre>
  
  <p>Thanks in advance</p>
