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.
