title: How to use Aspell in R?
body: <p>Before I used Aspell, I had installed aspell and english dictionary in terminal (OS X 10.9) . When I tried <code>&gt; aspell("duncan")</code> as exemplified by <em><a href="http://www.omegahat.org/Aspell/aspell.html" rel="nofollow">http://www.omegahat.org/Aspell/aspell.html</a></em>, console showed:</p>
  
  <pre><code>Error in file(con, "r") : cannot open the connection
  In addition: Warning message:
  In file(con, "r") : cannot open file 'duncan': No such file or directory
  </code></pre>
  
  <p>I thought it might because aspell{utils} might be different from aspell of Aspell package. Then I tried to install Aspell by <code>install.packages("Aspell", repos = "http://www.omegahat.org/R")</code> based on <em><a href="http://www.omegahat.org/Aspell/" rel="nofollow">http://www.omegahat.org/Aspell/</a></em> but R showed:</p>
  
  <pre><code>Warning: unable to access index for repository http://www.omegahat.org/R/bin/macosx/contrib/3.1
  
     package ‘Aspell’ is available as a source package but not as a binary
  
  Warning message:
  package ‘Aspell’ is not available (for R version 3.1.1) 
  </code></pre>
  
  <p>In addition, I am totally confused by <code>R CMD INSTALL Aspell_0.1-0.tar.gz</code>(<em><a href="http://www.omegahat.org/Aspell/" rel="nofollow">http://www.omegahat.org/Aspell/</a></em>). Where should I type and run it?</p>
  
  <p>How can I use Aspell in R normally? Or can your provide me a good manual?
  Thanks in advance.</p>
