This is a cut down version of my full record set.  Sometimes when I key 
formulas in I get ?ERROR back for a result after keying in c-c+c-c once 
I've completed the formula and hit tab.  If I do c-u+c-c+c-c that 
sometimes generated ?ERROR.  Other times I key in a formula and the cursor 
gets locked and I have to hit c-g to exit #+TBLFM: mode; I don't know 
what's actually happening when that situation arises since other than 
suddenly finding the cursor locked I can neither tell what state I'm in or 
if a few more keystrokes are needed or if I've generated an error 
situation.

The formula in question is the culprit in this case (at least as stated
there).

: $2=$2=vmean(@<..@>)

Second column is equal to the second column which is equal to the mean of
all the values in the second column (including the header "Sys").

If you change the table as follows:

| Date             |   Sys | Dia | Pul | Sugar |
|------------------+-------+-----+-----+-------|
| [2014-04-27 Sun] |   125 |  88 |  78 |    92 |
| [2014-04-28 Mon] |   102 |  88 |  86 |    92 |
|------------------+-------+-----+-----+-------|
| Averages:        | 113.5 |  88 |  82 |    92 |
#+TBLFM: @>$2..@>$>=vmean(@I..@II)

All the values will properly compute.  If you want to avoid the second
HLINE above Averages: then change =@II= to =@>>= (penultimate row)

Jon

Jonathan,

Your modified ecm in this case works.
Having applied the ecm to a larger file with seven additional 
calculation rows in it the averages are now displaying on the sums line.
I tried @>-7 at the start of the #+TBLFM: line and that generated about 
as many errors as someone's first efforts at a Cobol program.
I also put a printf format string into that TBLFM: line that rounds 
averages to two decimal places and also prints out right parens at the 
end of each result.  Is that an emacs-orgmode convention?  I think the 
2>$2 piece of the #+TBLFM: line tells emacs-orgmode to put that 
calculation's results on the last line of the file and in column 2.

Are these calculations elisp format?  If so, I didn't read the elisp 
section of the spreadsheet info for emacs-orgmode yet.

@> means last line, @>> is second to last, @>>> third to last and so on.
So for 7th from the bottom it would be @>>>>>>>.

Re: PrintF specification
Everything after the =;= is considered part of the specification, so the
=)= used to close the vmean is actually part of the specification.
Changing that to =vmean();%.2f= will correct it.



For your sample ECM (plus original data and one sample line to actually
confirm median works) you would work with the following (Apologies for the
very long TBLFM line):

I was unable to find a built-in to determine the mode.  I've found sample
functions on Stack Overflow that would calculate it based on a list, but
I'm not familiar enough with Org-Table format on how to go from cell
references =@I..@II= to a list of values for the sake of manipulating them.

The syntax is wrong - the format has to go *outside* the parens
of the function. Also the row spec is almost certainly wrong -
something like the following is needed (but see below for a more
exact specification of what the table looks like and what the
actual TBLFM line should be):

#+TBLFM: @>$2..@>$>=vmean(@I..@II);%.2f

The @I..@II restricts the range of rows to be considered to be between
the first and the second hline. IOW, the assumption is that you have
three areas in your table: a header line, followed by an hline, a number
of rows with data, followed by an hline and a number of rows containing
calculated statistics, followed by an (optional) hline - something like
this:

| Date                 |    Sys |   Dia |   Pul | Sugar |
|----------------------+--------+-------+-------+-------|
| [2014-04-27 Sun]     |    125 |    88 |    78 |    92 |
| [2014-04-28 Mon]     |    102 |    88 |    86 |    92 |
|----------------------+--------+-------+-------+-------|
| Averages:            | 113.50 | 88.00 | 82.00 | 92.00 |
| Counts:              |      2 |     2 |     2 |     2 |
| Maximums:            | 125.00 | 88.00 | 86.00 | 92.00 |
| Medians:             |        |       |       |       |
| Minimums:            |        |       |       |       |
| Modes:               |        |       |       |       |
| Standard Deviations: |        |       |       |       |
| Sums:                |        |       |       |       |
|----------------------+--------+-------+-------+-------|
#+TBLFM: @>>>>>>>>$2..@>>>>>>>>$> = vmean(@I..@II);%.2f :: @>>>>>>>$2..@>>>>>>>$> = vcount(@I..@II) :: @>>>>>>$2..@>>>>>>$> = vmax(@I..@II);%.2f

The only challenges left are to refer to the correct row and to find the
appropriate calc function for the statistic at hand.

Unfortunately, org mode is not particularly flexible in referring to
cells (although it is a *lot* more flexible than it used to be). In
particular, referring to the "Averages:" row can not be done simply
(afaik): it's the first row after the second hline, so you'd think that
you can refer to it as @II+1 but hline-relative references are not
allowed on the LHS, so the best that I could do is refer to it as the
eightth column from the bottom: @>>>>>>>> and similarly for the others -
looks like chicken scratchings (or what amounts to the same thing, Perl
:-) ).

With that caveat, the above TBLFM line will calculate the first three of
the eight statistics you want - the rest can be done similarly with the
calc functions vmedian, vmin, vmode, vstdev and vsum; but you can see
it's getting unwieldy, particularly since the whole thing has to be on
one line (or has that changed? I'm not keeping track any longer...)

I believe that you are (partially or completely?) blind, which makes
this all the more difficult: counting how many "greater than" signs are
in each of those row specs is a pain for anybody, but I can't even
imagine how a blind person would deal with it.

As Jonathan Leech-Pepin points out, there is no vmode - my mistake.

I think Jonathan is right that calc does not have a vmode. I thought it
did at first, but looking further I could not find any reference to it
in the calc manual or in emacs help. Why do you think it exists?

Re: searching for csv utilities

[Jude DaShiell]

First, I tried usinb multiple #+TBLFM: lines to do all of the math and 
that only did the first line of calculations which was the sums which 
appear last.  After replacing the double colons between calculation 
lines in the single line form of the #+TBLFM: line seven of the 8 lines 
worked correctly.  The vmode() function only returned zeros since the 
columns weren't sorted.  I did find a calc-sort function in the calc 
info and tried vmode(sort(@I..@II))%.2f (nested functions) and that also 
returned zeros on the mode line.  Must be some other way to use that 
function I'll have to search out.  Thanks much for the help on this 
project, it probably will be stolen from and used in other projects 
here.

My mistake, it should be vsdev or vpsdev.

I mispelled it the same way: I can never remember the right name.

Also, if one uses a format on an undefined function (e.g. using
vmode(@I..@II); %.2f), I get 0.0 as a result and the error is hidden -
if the format is omitted, the literal vmode([...]) appears in the table,
so in that case at least one gets a hint that something is wrong. That
probably qualifies as a bug, but I don't know how easy it would be to fix.

Yes. Anyway, Calc has its own formatter which can be a solution:

You may want to consider a slightly different approach. It may (or
maynot) be relevant depending on your context.

First, denormalize your table into a "fact table" (which is handy when
dealingwith cubes):

#+name: data
| date             | type  |   q |
|------------------+-------+-----|
| [2014-04-27 Sun] | Sys   | 125 |
| [2014-04-28 Mon] | Sys   | 102 |
| [2014-04-29 Tue] | Sys   | 115 |
| [2014-04-27 Sun] | Dia   |  88 |
| [2014-04-28 Mon] | Dia   |  88 |
| [2014-04-29 Tue] | Dia   |  88 |
| [2014-04-27 Sun] | Pul   |  78 |
| [2014-04-28 Mon] | Pul   |  86 |
| [2014-04-29 Tue] | Pul   |  85 |
| [2014-04-27 Sun] | Sugar |  92 |
| [2014-04-28 Mon] | Sugar |  92 |
| [2014-04-29 Tue] | Sugar |  95 |

Then using a package named "org-aggregate" (on Melpa) you can derivean
aggregated table:

#+name: aggr
#+BEGIN: aggregate :table data :cols "type vcount() vmean(q) vmax(q)
vsdev(q);f3"
| type  | vcount() | vmean(q) | vmax(q) | vsdev(q);f3 |
|-------+----------+----------+---------+-------------|
| Sys   |        3 |      114 |     125 |      11.533 |
| Dia   |        3 |       88 |      88 |           0 |
| Pul   |        3 |       83 |      86 |       4.359 |
| Sugar |        3 |       93 |      95 |       1.732 |
#+END:

If you want to rotate this table, apply a transposition on it(provided
by the same package):

#+BEGIN: transpose :table "aggr"
| type        |   |    Sys | Dia |   Pul | Sugar |
| vcount()    |   |      3 |   3 |     3 |     3 |
| vmean(q)    |   |    114 |  88 |    83 |    93 |
| vmax(q)     |   |    125 |  88 |    86 |    95 |
| vsdev(q);f3 |   | 11.533 |   0 | 4.359 | 1.732 |
#+END:

You can sort the "data" table on dates without changing theaggregation.

Thanks for reminding me (us?) about this package.  Very useful!

Re: searching for csv utilities

I spent time looking for vmode in info org using a regular expression 
search and couldn't find it either.  That capability is probably in R 
though it may be under another name.  I have emacs-ess package and R 
installed on this system though haven't used them yet.  I also found sbcl 
so if it gets too difficult to get stuff done with R I'll have an option 
open to start studying common lisp and write a mode function I can use 
with common lisp in conjunction with orgmode.

Interestingly, I did find pop_stdev() in postgresql but it turned out to 
be one of those situations like you were better off never having found 
that function since I managed to break a query that was working up until I 
added that extra code into it.  I was using aliases and pop_stdev() needs 
explicit casting to work at all for some reason.  That's what happens on 
learning curves every so often.
