title: R- Autoplot function
body: <p>Hi I am running a ggfortify package in R, that allows customisation of time series plots in R. </p>
  
  <p>See link <a href="https://cran.r-project.org/web/packages/ggfortify/vignettes/basics.html" rel="nofollow noreferrer">https://cran.r-project.org/web/packages/ggfortify/vignettes/basics.html</a>. </p>
  
  <p>The Link shows the example change of color on the plot:</p>
  
  <pre><code>library(ggfortify) 
  autoplot(AirPassengers, ts.colour = 'blue')
  </code></pre>
  
  <p>In my code I have installed the packaged and loaded the library for ggfortify, however it doesn't display this ts.colour function as I type it. </p>
  
  <p>My code:</p>
  
  <pre><code>autoplot(sales, ts.colour = 'blue')
  </code></pre>
  
  <p>resembles the above, but displays it in black, with the background the style should include but no difference to plot colour or thickness.</p>
