title: Update a data frame in shiny server.R without restarting the App
body: <p>Any ideas on how to update a data frame that shiny is using without stopping and restarting the application?</p>
  
  <p>I tried putting a <code>load(file = "my_data_frame.RData", envir = .GlobalEnv)</code> inside a reactive function but so far no luck. The data frame isn't updated until after the app is stopped.</p>
