You are, of course, entirely correct and, once again, I tip my hat to
the erudition of those who comment on this list. My initial
formulation, for a distance on a normed space inherited from the norm,
stands trivially, but as you rightly point out, I'm excluding many
interesting and possibly useful

Point of order, Mr. Chairman. (This is really *toadally* off topic;
my apologies, but I couldn't resist --- I trained as a pure mat
ut that's a discussion for another time and place --
but the function still returns a valid dist object for both d1 and d2.

You will note that I include the r-help list on each email on this

One order of the usual coming right up!
1 course of "Why does XXX not work for you?" a la francaise, where XXX
is, in your case, the Euclidean distance. Specifically, any metric
worth its salt (in a normed space) satisfies dist(a,b) = dist(a+c,b+c)
so why are negative values a problem?...

Hi,
I need to run a PCoA (PCO) for a data set wich has both positive and negative
values for variables. I could not find any distancecoefficient other than
euclidean distace running for the data set. Are there any other coefficient
works with negtive values.Also I cannot get summary out put (th
