title: relenium package: failed to create firefoxClass instance
body: <p>I am trying to use <a href="http://lluisramon.github.io/relenium" rel="nofollow">relenium package</a> to scrape some web content. So I installed packages as required in the documentation</p>
  
  <pre><code>install.packages("rJava")
  require(devtools)
  
  install_github('seleniumJars', 'LluisRamon')
  install_github('relenium', 'LluisRamon')
  </code></pre>
  
  <p>loaded packages (I probably did not need the first two; I tried with and without with the same result</p>
  
  <pre><code>#require(rJava)
  #require(seleniumJars)
  require(relenium)
  </code></pre>
  
  <p>When I am trying to instantiate firefox browser class</p>
  
  <pre><code>firefox &lt;- firefoxClass$new()
  </code></pre>
  
  <p>I am getting the following error message</p>
  
  <pre><code>`Error in exceptionTable[, 1] : subscript out of bounds`
  </code></pre>
  
  <p>How can I resolve this issue?</p>
