title: make_Weka_classifier("weka/classifiers/bayes/naiveBayes") and J48 not working on my R?
body: <p>I tried googling around but can't find any answer to this problem.</p>
  <p>Currently trying to use Naive Bayes on R using Weka but am getting this error and I also tried using J48 to visualize a decision tree but that's not working out either.</p>
  <blockquote>
  <p>Error in make_Weka_classifier(&quot;weka/classifiers/bayes/NaiveBayes&quot;) : could not find function &quot;make_Weka_classifier&quot; for the Naive Bayes and Error in J48(pep ~ var1 + var2 + var3, data=dataset) : could not find function &quot;J48&quot;</p>
  </blockquote>
  <p>Not sure what's wrong but I did these 2 lines at the start of my code:</p>
  <pre class="lang-r prettyprint-override"><code>install.packages(&quot;RWeka&quot;)
  library(RWeka)
  </code></pre>
  <p>Hope I could get some help on this, thanks!</p>
