title: Trouble with 'fitdistrplus' package, t-distribution
body: <p>I am trying to fit t-distributions to my data but am unable to do so. My first try was</p>
  
  <pre><code>fitdistr(myData, "t")
  </code></pre>
  
  <p>There are 41 warnings, all saying that NaNs are produced. I don't know how, logarithms seem to be involved. So I adjusted my data somewhat so that all data is >0, but I still have the same problem (9 fewer warnings though...). Same problem with sstdFit(), produces NaNs. </p>
  
  <p>So instead I try with fitdist which I've seen on stackoverflow and CrossValidated:</p>
  
  <pre><code>fitdist(myData, "t")
  </code></pre>
  
  <p>I then get</p>
  
  <pre><code>Error in mledist(data, distname, start, fix.arg, ...) :
  'start' must be defined as a named list for this distribution
  </code></pre>
  
  <p>What does this mean? I tried looking into the documentation but that told me nothing. I just want to possibly fit a t-distribution, this is so frustrating :P</p>
  
  <p>Thanks!</p>
