title: Add labels to X axis
body: <p>I made a plot and it turned out fine besides the X axis labels. I want all the labels to be shown on the plot and for some reason the plot only shows some of them.</p>
  
  <p>Following my code:</p>
  
  <pre><code>plot(seq(2001,2015,1), sunday_mean, pch=16,
       main="Mean values for all the roads going in Beer Sheva",
       xlab="Year",
       ylab="Appearences")`
  </code></pre>
  
  <p>And here, the plot I get:
