title: Error: Attempt to apply non-function in Oracle R enterprise
body: <p>I'm currently trying to implement <strong>support vector machine</strong> algorithm for classification and anomaly detection using <strong>Oracle R Enterprise (ORE)</strong>. I've installed the ORE packages in RStudio
  and as a sample, I'm trying to execute the following code given in <a href="http://docs.oracle.com/cd/E11882_01/doc.112/e36761/mining.htm#CEGGGHAE" rel="nofollow">Oracle Docs</a>:</p>
  
  <pre><code>library(ORE)      
  m &lt;- mtcars
  m$gear &lt;- as.factor(m$gear)
  m$cyl  &lt;- as.factor(m$cyl)
  m$vs   &lt;- as.factor(m$vs)
  m$ID   &lt;- 1:nrow(m)
  MTCARS &lt;- ore.push(m)
  </code></pre>
  
  <p>And I got the following error:</p>
  
  <pre><code>Error in .ore.obj() : attempt to apply non-function
  </code></pre>
  
  <p>I think it is because <code>ore.push()</code> is not recognized but When I searched in the ORE Reference Manual it is clearly defined with an example.
  So, what could be its solution?</p>
