title: Radian measure in sin in R?
body: <p>I want to calculate the following in R:</p>
  
  <p>sin(52.517°)</p>
  
  <p>and this should be equal to 0.79353. But when I code</p>
  
  <pre><code>sin(52.517)
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>0.777119
  </code></pre>
  
  <p>So how can I get the 0.79353. I am not good in math, but I know something is not working with degrees and the radian measure here in R.</p>
