[R] mode

[Murray Jorgensen]

Opps! This is what I should have written:

The mode of a data vector x might be defined as the limit of m_p as p 
tends to zero from above and where m_p is the m minimizing
sum(abs(x - m)^p).  I would not expect the mode so defined to be of much 
use in data analysis, nor would it be easy to compute.

[Thanks to Duncan Murdoch for noticing the missing ^p .]
