Re: [O] searching for csv utilities

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.
