title: Plotting multiple time-series in ggplot
body: <p>I have a time-series dataset consisting of 10 variables.</p>
  
  <p>I would like to create a time-series plot, where each 10 variable is plotted in different colors, over time, on the same graph. The values should be on the Y axis and the dates on the X axis. </p>
  
  <p><a href="https://dl.dropbox.com/u/22681355/co.csv" rel="noreferrer">Click Here</a> for dataset csv</p>
  
  <p>This is the (probably wrong) code I have been using:</p>
  
  <pre><code>c.o&lt;-read.csv(file="co.csv",head=TRUE)
  ggplot(c.o, aes(Year, a, b, c, d, e,f))+geom_line()
  </code></pre>
  
  <p>and here's what the output from the code looks like: <img src="https://i.stack.imgur.com/FPvTT.png" alt=""></p>
  
  <p>Can anyone point me in the right direction? I wasn't able to find anything in previous threads.</p>
  
  <p>PROBLEM SOLVED, SEE BELOW.</p>
  
  <p>One additional thing I would like to know:</p>
  
  <p>Is it possible to add an extra line to the plot which represents the average of all variables across time, and have some smoothing below and above that line to represent individual variations?</p>
