Hello all--

I'm looking for help in setting up a calculation in a table in org mode.
 I'd like to keep a running average of my past three days worth of
measurements.  Something like

|------------------+-----------------+-----------------|
| Date             | TV Time (hours) | Running Average |
|------------------+-----------------+-----------------|
| <2006-06-24 Sat> |               1 |                 |
| <2006-06-25 Sun> |             1.5 |                 |
| <2006-06-26 Mon> |              .5 |               1 |
| <2006-06-27 Tue> |               3 |            1.66 |
| <2006-06-28 Wed> |             2.5 |               2 |
|------------------+-----------------+-----------------|

I just did the numbers for running average in my head-- I'm hoping for
help with a formula that will get the mean for the last three rows of
the `TV Time' column.  I tried using $3=vsum($2&3-1), but this didn't
work.

Is there a syntax for accessing row ranges of other columns for a
calculation?  If not, can anyone suggest an elisp formula that will
accomplish this?

If a helpful soul is feeling especially generous, is there also a way to
set this table up that will calculate the new running average every time
I enter a new date's measurement?  Extra credit if you use Carsten's
constants.el to provide units in the measurment column and the
calculated column ;)

Thanks for any help,
/au

calc may be your friend here.

We should create a couple recipes for passing a row or column
from org to calc and getting it back -- then we can do all the
computes on the calc side.

Calc has an "embed" mode that works very well out of the box
inside text LaTeX and consequently org files; would be nice to
take org's table minor mode and couple it with calc's vector
capabilities

Unfortunately, this is beyond the current syntax
envelope for table equations in org-mode.

I could widen that envelope, but not soon.
