title: Removing Row Numbering in R
body: <p>Just say I have a csv file that looks something like this:</p>
  
  <pre><code>name     number of cats
  Bob            1
  Janet          0
  Margaret      47
  Tim            2
  </code></pre>
  
  <p>And I load it into R doing this:</p>
  
  <pre><code>cats &lt;- read.csv("cats.csv")
  </code></pre>
  
  <p>If I then open "cats" in R, I get a numbering like this: </p>
  
  <pre><code>  name     number of cats
  1 Bob            1
  2 Janet          0
  3 Margaret      47
  4 Tim            2
  </code></pre>
  
  <p>Similarly, if then write the csv the numbering is retained in the file. </p>
  
  <pre><code>write.csv(cats, "cats_with_numbers.csv")
  </code></pre>
  
  <p>I tried deleting the column, but that didn't work. Any help is appreciated. :)</p>
