<div dir="ltr">I disagree with the criticism of data.table's complexity (in the OP). There's nothing wrong with overloading the syntax (that is what CS people call it, right?). As long as Matthew's in control of it, it's likely to have some internal consistency (which, of course, he could explain). However, I like the suggestion to add options (defaulting to something globally adjustable) to disable some of the overloading. Along similar lines (I think), I find unique.data.table very unintuitive. I can see how it could be useful, but strongly prefer base::unique for my current applications.<div>
<br></div><div>Anyway, I have nothing particular to say about the piece of syntax you all are currently discussing. I just registered with this list to chime in here, instead of further cluttering SO (where eddi answered one of my questions yesterday). These emails sure are wide; must be like 1500px! Interesting to try out this ancient mailing-list form of communication. Please let me know if I should be using "Reply All" or actually quoting that massive thread (as everyone else seems to be doing with each post).</div>
