Frequency conversion for sample

[Katjes]

I would like to convert a monthly series to a annual one, but selecting the conversion method for 1990-1995 average and for 1996 1996 the last value.
I do not select the conversion method the following code works for the average part, and it works.

Code: Select all

wfcreate(page=page1) m 1990 2010 series y=nrnd pagecreate(page=page2) a 1990 2010 copy(smpl="1990 1995") page1\y page2\y show y

If I try the last value procedure, the smpl is completly ignored and the whole series is copied to the annual sheet.

Code: Select all

wfcreate(page=page1) m 1990 2010 series y=nrnd pagecreate(page=page2) a 1990 2010 copy(c=l,smpl="1996 1996") page1\y page2\y show y

Now I decided to take a indirect way with a help series, but I maybe there is a more intuitive and less complicated way????

Code: Select all

wfcreate(page=page1) m 1990 2010 series y=nrnd pagecreate(page=page2) a 1990 2010 copy(smpl="1990 1995") page1\y page2\y copy(c=l) page1\y page2\y1 'genr a help series y1 pageselect page2 smpl 1996 1996 y=y1 delete y1 smpl @all show y

The smpl option of the copy command only works when you're performing a match-merge copy, not a dated copy.
