title: Changing X-axis values in Time Series plot with R
body: <p>I'm a newer R user and I need help with a time series plot. I created a time series plot, and cannot figure out how to change my x-axis values to correspond to my sample dates. My data is as follows:</p>
  
  <pre><code> Year  Month  Level
   2009   8     350
   2009   9     210
   2009   10    173
   2009   11    166
   2009   12    153
   2010   1     141
   2010   2     129
   2010   3     124
   2010   4     103
   2010   5     69
   2010   6     51
   2010   7     49
   2010   8     51
   2010   9     51
  </code></pre>
  
  <p>Let's say this data is saved as the name "data.csv"</p>
  
  <pre><code>data = read.table("data.csv", sep = ",", header = T)
  data.ts = ts(data, frequency = 1)
  plot(dat.mission.ts[, 3], ylab = "level", main = "main", axes = T)
  </code></pre>
  
  <p>I've also tried inputing the <code>start = c(2009, 8)</code> into the <code>ts</code> function but I still get wrong values</p>
  
  <p>When I plot this my x axis does not correlate to August 2009 through Sept. 2010. It will either increase by year or just by decimal. I've looked up many examples online and also through the ? help on R, but cannot find a way to relabel my axis values. Any help would be appreciated.</p>
