title: RStudio not displaying any output
body: <p>When I write a script in RStudio, and run it, it isn't displaying any output. However, if I run the commands directly in console, it's working.</p>
  
  <p>For example, if I have a file called script1.R which has the following code:</p>
  
  <pre><code>r = 5 * 25 * 2
  r
  </code></pre>
  
  <p>When I do</p>
  
  <pre><code>source('~/Desktop/script1.R')
  </code></pre>
  
  <p>nothing happens. However, if I just type those two lines into console, it's working fine. What can I do to fix this? I have RStudio Version 0.98.1103 and R 3.1.2.</p>
