title: writeLines not recognising my ratio R
body: <p>I am trying to use writeLines on a ratio of two columns in my dataset-</p>
  
  <pre><code>Name  Height Length
  RLM1   200     80
  FLM2   300     200
  LOP1   170     30
  KIM1   320     230  
  </code></pre>
  
  <p>So for my code, I have tried the following-</p>
  
  <pre><code>writeLines(as.character(df[df$Height/df$Length &gt;2, "Name"]), con='Names.txt')
  </code></pre>
  
  <p>The desired output is if the ratio of height:length is greater than 2, the Name column prints its value. So here, I want RLM1 and LOP1.</p>
  
  <p>The issue I am having is that it is saying error, invalid 'text' argument, which I assume is due to the / in the code but I am not sure. </p>
  
  <p>Is there a way around this?</p>
