title: File path issues in R using Windows ("Hex digits in character string" error)
body: <p>I run R on Windows, and have a csv file on the Desktop. I load it as follows,</p>
  
  <pre><code>x&lt;-read.csv("C:\Users\surfcat\Desktop\2006_dissimilarity.csv",header=TRUE)
  </code></pre>
  
  <p>but the R gives the following error message</p>
  
  <blockquote>
    <p>Error: '\U' used without hex digits in character string starting "C:\U"</p>
  </blockquote>
  
  <p>So what's the correct way to load this file. I am using Vista</p>
