Thanks, Allin, for reminding us (me) of this function, which wasn't
really on my radar. Two comments about the doc:
- This is another example where X13 isn't mentioned yet. Do I understand
correctly that for the default settings X12 and X13 should produce
identical results?
- It's not clear from the doc what it means that the function will fail.
Or to put it differently, if it's a hard error and the script cannot
continue, then it's a bit of a problem, I'd say. But I'm not sure
whether "catch" can be used, since it's a function and not a command.
OK, some testing with an artificially constant series:
<hansl>
nulldata 200
setobs 4 1:1 --time-series
series x = 2
series xSA = deseas(x) # no error, series is produced
</hansl>
Hm, since I'm not getting an error even there, it's a bit hard to
analyze... Could it be that the doc is not up to date?
It would be quite easy to add an optional bundle-of-options argument
to deseas(), to give as much control over the processing as is offered
by the GUI interface (perhaps more, if anyone's so motivated).
I agree with Jack, this sounds very desirable...
thanks
