PSPP-BUG: Re: [bug #30008] Aggregate data

[Fredrik Clementz]

Some feedback on the aggregate command! It seems most stuff is in place. Uncertain if you aim for a practical look or a cloned look or your own look. Anyway, there are 


1. The default size of the variable listbox (at least in windows) is way too small. It is so narrow that the first thing that has to be done to work with this window is expanding it in width. Therefor may I suggest that it should be wider as default so that one doesn't have to expand it every time? Possibly making the entire window just a little big bigger as well.

2. THe most common function I use aggregate for is simply looking for "duplicates" or similar. Now how this is done is simply using a number of variables that I push in as break variables. THen I usually tick in "Number of cases" and run it. However, in PSPP, there is no "Number of cases box" and just adding the variables to break won't allow me to press ok.  I believe this is the most common use of this function which is likely why SPSS added this quick tickbox instead of fiddling around with the more daring "functions" that more experienced users deal with (Ehrm, not to mention more experienced tend to fall to Syntax mode). I would suggest relooking how this is done to not make it differ from SPSS to much as I really believe there approoach is better than ours at the moment.

3. If we'd really like to go a bit beyond SPSS which I personally would enjoy, one of the functions I would appreciate is to add the function "random". So when aggregating a dataset and there are 2 similar cases, how about choosing a random value from these. Would be really useful. 

4. Assuming we'll keep the way functions are added now (I really see the benefit of efficiency not having popups over popups), may I suggest doing a similar grouping of options witha  header as done in SPSS. Like -Summary- or -Specific- Etc.... Food for thought, this one is discussable I agree.

5. I note that we have "replace the current dataset with the aggregated variables" while SPSS has "create a new dataset containing only the aggregated variables" with the option of giving it a name. Now I would believe that these 2 are similar? Just that our current name implies removing the current dataset in favour of the aggregated. Think some clarification would be nice.

I hope this is some feedback. I believe no 1 and 2 are really important, while the others are more like to have or discuss.


Cheers,

F

Would love to try it out, just that the adding of this command in the menus are not reflected in the latest PSPPire build from Awardspace. If someone could make yet another build there, I'd love to download and give feedback.

Follow-up Comment #2:

I've pushed a change implementing this feature to the master repository.
There may be a few wrinkles yet to be ironed out, but it basically works.

Any feedback is highly appreciated.
