title: Issues installing "quanteda" in R
body: <p>I am trying to install quanteda package for text-mining in R (ver. 3.2.2.) running on Ubuntu 15.10.
  The message I receive is the old classic:</p>
  
  <pre><code>  `Warning in install.packages :
     package ‘quanteda’ is not available (for R version 3.2.2)`
  </code></pre>
  
  <p>Yet, I have tried with dependencies</p>
  
  <pre><code>   install.packages("quanteda", dependencies = T)
  </code></pre>
  
  <p>and suggestions from github</p>
  
  <pre><code>   devtools::install_github("kbenoit/quanteda", ref = "03ae172")
  </code></pre>
  
  <p>without any result.</p>
  
  <p>Any workaround? </p>
