Dear Sir or Madam, LO calc supports the copying of array formulas as described in http://help.libreoffice.org/Calc/Array_Functions#Copying_Array_Formulas . However I'm missing the automatic adjustment of array formulas: If you "drag" a "normal" formula, say "=SUM(A1:A$100)" to the cell below, the formula reads "=SUM(A2:A$100)". That's what I'm looking for for array formulas. It could be that I just don't know how to do that. In that case, the user interface could be enhanced. If Libreoffice is missing this feature, I'd love to see it implemented in a future version. Keep up with your good work!

Failed to reproduce on LibreOffice 3.4 340m1(Build:103) for OpenSuse Linux. Dragging formula for SUM works, except it shifts the cell range from A1 to A100 to A2 to A101, which works as expected.

Perhaps I need to clarify: The "dragging" of "=SUM(…)" works fine. I'm looking for "dragging" of /array/ formulas like "{=SUM((A1:A100>=90)*(A1:A100<=120)*(A1:A100))}". does that work on your LO 3.4, Jeffrey?

I tried it on LO 3.4.3 and it does not work neither. Having the array formula in cell D1 and dragging it to D2 I get an error like #NAME? in both cells because the function changes to "sum" instead of "SUM". Beside, it looks like it would not copy incrementially but expand the array to the next cell.

Addition to comment 3: The error #NAME? only results if functions are involved with the array formula. If only cell addresses are involved there is no error, but it still does not copy incrementially but only expands the array to the next cell. It seems like this is wanted? Maybe it is!

For array formulas simple dragging adjusts the output array. To get copy-drag you have to hold Ctrl-key while dragging.

After an update to 3.4.3, it indeed seems to be fixed :) PS: @Regina: In my case, it's the other way around (ctrl adjusts, simple dragging copies) :)

I agree, copy-drag works as expected when holding the Ctrl-key while dragging. I didn't carefully read the help for "Copying Array Formulas". But simple dragging doesn't work properly. It works if the array formula does not contain functions like SUM. Otherwise I get an error: #NAME? in every cell of the array range because the function changes from "SUM" to "sum". It can be fixed by editing the array range and changing the function back from "sum" to "SUM". But this is rather a workaround, it should work in the first step.
