Christos Argyropoulos MD, PhD<p>Breaking data.table in <a href="https://mstdn.science/tags/rstats" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rstats</span></a>.<br>This was noticed by our brilliant data analyst Hamza Mir, when analyzing a 10 <a href="https://mstdn.science/tags/gigarow" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gigarow</span></a> <a href="https://mstdn.science/tags/EMR" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EMR</span></a> dataset. <a href="https://mstdn.science/tags/fread" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fread</span></a> will assign a name to each row, i.e. the row number. If the number of lines exceeds 2^31, then a long vector of names has to be generated and R does not support those apparently (yet).<br>Reproducible example (<a href="https://mstdn.science/tags/Perl" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Perl</span></a> code to generate a very large dataset on left, and <a href="https://mstdn.science/tags/rstats" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rstats</span></a> output with failure). <br>ALT-text for code.<br>See also <a href="https://stackoverflow.com/questions/76456801/data-tablefread-fails-for-larger-file-long-vectors-not-supported-yet" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">stackoverflow.com/questions/76</span><span class="invisible">456801/data-tablefread-fails-for-larger-file-long-vectors-not-supported-yet</span></a></p>
