he way rsup is set up is interesting in that the loading bar is shown or hidden from the R server. One could set it up differently however. Perhaps, instead of having to trigger the loading bar from the server it could all be handled automatically: showing the bar when the server is computing or redrawing things and hiding it when the server becomes idle again.</p>
