title: Can't Read Data from CSV file to R Markdown Shiny Document
body: <p>I am experimenting with the R Markdown Shiny documents for interactive reporting. First trouble got is to read data from local csv file.</p>
  
  <p><code>{r, cache=TRUE}
  raw1&lt;-read.csv("data/set1.csv")
  splits &lt;- unique(raw1$split)
  </code>
  The error message I have is " Error in file(file, "rt") : cannot open the connection".</p>
  
  <p>There is no issue to use the above code to read data in regular R Markdown documents. Can anyone help the best practice to create interactive reporting using Shiny Document?</p>
