Hi,
When using VECTOR ELM MAP function, would it be possible to avoid the error message (due to mapping outside the range) and set those :NA: to be some value such as 0? Basically I want to "shift" the values of a subscripted constant A to a subscripted constant B, by 5 subscript units. Something like the following:

A [00] = 0.1
A [01] = 0.2
A [03] = 0.3
A [04] = 0.4
A [05] = 0.5
A [06] = 0.6
A [07] = 0.7
A [08] = 0.8
A [09] = 0.9
...
A [99] = 9.9
A [100] = 10

By using VECTOR ELM MAP, with the offset being -5, I want to have:

B [00] = 0
B [01] = 0
B [03] = 0
B [04] = 0
B [05] = 0
B [06] = 0.1
B [07] = 0.2
B [08] = 0.3
B [09] = 0.4
...
B [99] = 9.4
B [100] = 9.5

The shift works out for B [06] to B [100]. However, error messages showing "ERROR: VECTOR_ELM_MAP outside array bounds computing..." come up, and the values for B [00] to B [05] are "--" instead of 0.

It is not surprising that the error message come up, because there are no subscripts before [00]. But is it possible to somewhat suppress the error messages and assign 0 to B [00] to B [05] ?

Finally, is VECTOR ELM MAP the best method in this case? Wondering whether there is some other way that is more efficient/elegant.

Thank you so much.

You cannot suppress the error (as it is an error).

One alternative would be to do something like I've done in the attached model.

You could use VECTOR SELECT, which has an argument for missing values.

Thanks a lot Administrator. Please could you explain why a Sum function is needed here?

Thanks.

Hi

go to

viewtopic.php?f=2&t=3192&p=22055&hilit= ... map#p22055


it will ho to avoid using the tricky and Dangerous vector elm map function.

It's only there to loop over the whole subscript range.
