title: How to acces stl() output values in R
body: <p>I know this is a simple question for skilled user of R, but I don't know how to access the stl output. I googled it for a while but i didn't found any tutorial. This is what i mean, I have this little sequence of command</p>
  
  <pre><code>   dd&lt;-read.table('data.dat')
     ddts&lt;-ts(dd,start=1,freq=300)
     stldd&lt;-stl(ddts,s.window='periodic')
  </code></pre>
  
  <p>know i want to perform a fit on the trend part of stldd, but I don't know how to access it.</p>
