<p class="MsoNormal">First of all, I really like Rccp and would like to thank you all for your work.</p>
<p class="MsoNormal">I try to debug an cpp file, which I source from R, using the lldb debuger.</p>

<p class="MsoNormal"><b>How it is possible to get the values of the vector in lldb?<o:p></o:p></b></p>
<p class="MsoNormal">I think, that the struct CharacterVector only stores the Memory address of the data.</p>

<p class="MsoNormal">I have the same problem with NumericVectors, which are stored as double.</p>
<p class="MsoNormal">If I tried to access them (format as double, 2072 bytes) but I didnīt get the expected values:</p>
