<p>A workspace containing most of the results has been saved as KDD2009.Rdata and can be loaded in R with the command:</p>
<div class="sourceCode"><pre class="sourceCode r"><code class="sourceCode r"><span class="kw">load</span>(<span class="st">&#39;KDD2009.Rdata&#39;</span>)</code></pre></div>
<p>(note you will have to re-load various libraries like ROCR to perform some of the steps).</p>
