<div>Yet sometimes only subsets of a file is really needed, subsets that could fit into RAM.</div><div> </div><div>So what about adding a grep option to fread that would allow to load only lines that matches a regular expression?</div>
<div> </div><div>I'll add a request if you think the idea is worth implementing.</div><div> </div><div>Cheers</div><div> </div>
