[R] alas, no vecnorm

[Faheem Mitha]

I wanted a function that would give the euclidean distance of a vector. 

Then I was happy, because I found vecnorm listed on pg 55 of V&R (3rd
edn) which I had just bought today.

Then I was sad, because R did not have vecnorm.

Then I was happy again, because I bethought myself that I could copy the
function vecnorm from splus to my code.

Then I was sad again because R complained

> vecnorm(v)
Error in .Fortran("d2norm", as.integer(length(x)), as.double(x), value =
double(1)) : 
	C/Fortran function name not in load table

So, after this tempest of emotion, the question still remains: does R have
this function under another name, or was it simply overlooked?

                              Best regards, Faheem Mitha.
