Apologies, that was supposed to be double the size not triple, 99% of the
survey data are integers.
But I suppose that is alright, space doesn't seem to be a problem.

Thank you very much for the examples, they do seem to cover the basics
indeed.
(that is what I meant when I wrote there might be a way without tagging
NAs).

Will take it from there, best wishes,
