Hello,

While creating many transformed versions of variables in and outside of loops, I've been seeing this error lately:

Error in set(MapYrCtyAllGradeMiAreaPopSt, NULL, "StYearHwyMiGradeAllLogPerStPop",  : 
  Internal logical error. DT passed to assign has not been allocated enough column slots. l=100, tl=100, adding 1

I found out to resolve it from this Stack Overflow post:
https://stackoverflow.com/questions/29615181/r-warning-when-creating-a-long-list-of-dummies

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.

Also, I was wondering if you could explain why I ran into the error using set(), but not :=?

Thanks,

Zach
