title: CHAID package installed from source in R
body: <p>I have installed <code>CHAID</code> package in R for Windows in the following way:</p>
  
  <ol>
  <li>installed the <code>Rtools31.exe</code></li>
  <li>installed the package from source: <code>install.packages("CHAID", repos = "http://R-Forge.R-project.org", type = "source")</code></li>
  </ol>
  
  <p>When I try to see the help documentation for CHAID I run : ?CHAID()
  the following error message appears:</p>
  
  <pre><code>"Error in .helpForCall(topicExpr, parent.frame()) : 
    no methods for ‘chaid’ and no documentation for it as a function"
  </code></pre>
  
  <p>This means the <code>CHAID</code> package hasn't been installed?
  when I run the <code>installed.packages()</code> the following line appears:</p>
  
  <pre><code>        Package                                        LibPath   Version   Priority     
  CHAID   "CHAID"  "C:/Users/JJJJJJ/Documents/R/win-library/3.1"   "0.1-1"         NA        
  </code></pre>
