Yeah I'll try that, see if it gives me any clues.
Is there a way to run your code manually for debugging via the command
line with the JS engine the way couch calls it to build the view? (like
an interactive mode of couchjs)

Reduce functions can be tricky. My best advice: try log()'ing all your
input and intermediary results; the answer usually jumps out to ya.

Hi,
I have a reduce function like this:
[snip]
So for some reason if there is only 1 element to be reduced, on the line of
res[v_n]={'mi':v,'ma':v,'c':1,'t':v};
v becomes v={} and not the actual number. Any ideas why?
I tested the reduce function with the command line 'js' and send it the
above test keys manually as function argument and then it does result in the
correct return:
"01:00:000074" -> {raw: {mi: -0.213, ma: -0.213, c: 1, t: -0.213}}
"01:00:000084" -> {raw: {mi: -0.213, ma: -0.213, c: 1, t: -0.213}}
Sounds like you need to specify group_level; Try playing around in
Futon, you'll see a group_level dropdown.

Why would I need a group_level parameter?
My key is a simple string "01:00:000074".
Its my values don't get correctly generated by couchjs, since it does out but
proper values in normal commandline js.
var v = new Number(values[val][v_n]);
if(res.hasOwnProperty(v_n)){
res[v_n].mi = Math.min(v,res[v_n].mi);
res[v_n].ma = Math.max(v,res[v_n].ma);
res[v_n].c++;
res[v_n].t += v;
}else{
res[v_n]={'mi':v,'ma':v,'c':1,'t':v};
}
It seems that in the above part in the 'else' case the v isn't a number but an
empty object {}
