title: All my plots in Rstudio just show up as gray boxes?
body: <p>I am using ggplot and geoms to show my data, but the plot sidebar area just shows a gray box with the <code>x</code> and <code>y</code> axis correctly labeled. </p>
  
  <p>Here is the output image:</p>

  <p>The code which made the plot:</p>
  
  <pre><code>ggplot(Wc, aes(y = popsafe, x = rnground)) +
     geom_jitter(aes(col = me)) +
     geom_smooth(method = "lm", se = FALSE, col = "black")
  </code></pre>
