What did I do wrong with this #+TBLFM: line?
Two things:
o as Christian Moe pointed out, calc does not provide a vmode() function.
o the separator lines in the formulas have to be specified using capital
I letters.
Here is an implementation of vmode - afaict, it works correctly but
that may be because I've only tested it on a single set of data. If
you find something wrong, please let me know.

I cribbed heavily from the implementation of vmedian. Although there is
no key binding, you can even use the above in an interactive Calc
session, by entering the formula in algebraic form. I yanked the vector
twice onto the Calc stack and then entered 'vmode($) with the following
result:
