title: Textwrapping long string in knitr output (RStudio)
body: <p>I have a long vector string (DNA sequence) of up to a couple of thousand sequential characters that I want to add to my knitr report output. RStudio handles the text wrapping perfectly in the console but when I generate the knitr html output I can see only one line of text and it just runs off the page. </p>

  <p>Any way of adjusting knitr output to wrap text?</p>
  
  <p>Thanks.</p>
