What do you mean exactly? Non-overlapping samples? Different
periodicities? Both? Something else altogether?
Here are some self-contained examples:
<hansl>
nulldata 100 # same example data to be joined
setobs 4 2000:1
series x = normal()
store file1.gdt
nulldata 40 # shorter sample
setobs 4 2000:1
join file1.gdt x # doesn't work
nulldata 120 # longer sample
setobs 4 2000:1
join file1.gdt x # doesn't work
nulldata 100
setobs 4 1990:1 # shifted but overlapping sample
join file1.gdt x # works but is WRONG
</hansl>
With respect to the last example I know you are going to say it's a
feature not a bug, and the responsibility of the user. But I find this
worthy of at least a warning message. And in any case I was originally
asking about the non-working cases.
thanks,
