title: How do you pass parameters to a shiny app via URL
body: <p>In web browsers you pass parameters to a website like</p>
  
  <p>www.mysite.com/?parameter=1</p>
  
  <p>I have a shiny app and I would like to use the parameter passed in to the site in calculations as an input.  So is it possible to do something like www.mysite.com/?parameter=1  and then use input!parameter?</p>
  
  <p>Can you provide any sample code or links?</p>
  
  <p>Thank you</p>
