title: delete the first line of a .txt file with R
body: <p>I have a lot of very large <code>txt-files</code> that have a header I would like to remove.<br>
  Is there a way to do this without reading in the entire file?<br>
  Possibly using the <code>system()</code> command?<br>
  I found some ideas <a href="https://unix.stackexchange.com/questions/96226/delete-first-line-of-a-file">here</a> but I haven't been able to make them work. I am using Windows 7 and R Version 3.2.2.</p>
  
  <p>Here is what I have tried:</p>
  
  <pre><code>&gt; systCommand &lt;- paste0("echo '$(tail -n +2 ",  myFilePath, ")' &gt; ", myFilePath)
  &gt; system(systCommand, intern=T)
  Error in system(systCommand, intern = T) : 'echo' not found
  </code></pre>
  
  <p>I am pretty sure that this is because I am using windows?</p>
