<div><br></div>
<div>While creating many transformed versions of variables in and
outside of loops, I've been seeing this error lately:</div>
<div><br></div>
<div>
<div>Error in set(MapYrCtyAllGradeMiAreaPopSt, NULL,
"StYearHwyMiGradeAllLogPerStPop", : </div>
<div> Internal logical error. DT passed to assign has not
been allocated enough column slots. l=100, tl=100, adding 1</div>
</div>

<div>I found out to resolve it from this Stack Overflow post:</div>

</div>

<div>Which directed me to the alloc.col help page. I mainly wanted
to write to suggest making the error a bit more
informative/helpful, e.g. directing the user to look at
alloc.col/trulength help page.</div>
<div><br></div>
<div>Also, I was wondering if you could explain why I ran into the
error using set(), but not :=?</div>
<div><br></div>
<div>Thanks,</div>
