title: Plotting Time Series
body: <p>I'm working on 16 world indices over three year and i want to make a plot from these 16 indices. </p>
  
  <pre><code>all&lt;-read.table("C.../16indices.txt")
  dimnames(all)[[2]]&lt;-c("Date","BEL 20","CAC 40","AEX","DAX","FTSE 100","IBEXx 35","ATX","SMI","FTSE MIB","RTX","HSI","NIKKEI 225","S&amp;P 500","NASDAQ","Dow Jones","BOVESPA")

  <p>Problems</p>
  
  <ol>
  <li>My dates are written in the form "2009-01-05". I want only "2009" to appear otherwise i would have to many jumps. </li>
  <li>For example the prices from the BOVESPA go from 40.000,15 to 60.000,137. How do I get nice y-labels? For instance 40.000, 45.000,...,60.000.</li>
  <li>How do i get 16 of these plots in one nice figure/plot?</li>
  </ol>
  
  <p>I'm not used to work with R. I tried something like this but that didn't work...</p>
  
  <pre><code>plot(all[1,],all[,2])
