title: R shiny reactive return more than one object
body: <p>I am making use of the example provided in in the answer to this question: <a href="https://stackoverflow.com/questions/17703711/shiny-reactivity">Shiny Reactivity</a></p>
  
  <p>They make use of two return statements in the reactive function. I believe return(x) is just a mistake. However, I am wondering if I can return more than one object with one reactive statement?</p>
