title: Rstudio - plots not showing and plots menu grayed out
body: <p>I'm using Rstudio Version 1.0.136.  I'm trying to plot some data and when I execute the code nothing shows up in the 'Plot' pane and the 'Plots' drop down menu is grayed out.  Any suggestions?</p>
  
  <p>EDIT:</p>
  
  <pre><code>&gt; dev.off()
  null device 
            1 
  
  &gt; dev.cur()
  null device 
            1 
  </code></pre>
  
  <p>I tried restarting R and then ran this code and got this error message:</p>
  
  <pre><code>&gt; library(ggplot2);qplot(mpg, hp, data = mtcars)
  Warning message:
  R graphics engine version 12 is not supported by this version of RStudio. The Plots tab will be disabled until a newer version of RStudio is installed. 
  </code></pre>
