Very weird spmap problem: "master data not sorted"

[Andrea Berni]

Hello all

Suddenly, I am having some unexplained problem with spmap: syntax which previously was working now does not anymore, reporting the error "master data not sorted". Now, I know for sure that sorting _ID in the master data is kind of unrequested, since I can run spmap regardless of the sorting of _ID in other .dta files which still work. This seems to be quite random and sudden: some .dta files no more work with spmap, always reporting such error.

Do you have any idea? I am quite lost now.

Thanks in advance, kind regards.

Oh well, kinda solved: the "master data" is the coordinates dataset actually (I thought it was the "real master" instead, the one where I run spmap from). It took just to "re-sort" things in the coordinates datafile and save again, even if obs were already sorted for good, of course! No real change occurred, it is just like STATA "needed to know" the data were sorted out correctly already, which is kind of strange, but fine, problem solved, thanks!
