R help - Jun 2010 - variation

Hi list
I am a new user of R. I ask for some "beginner" question

I am searching if there is any function that computes the variation of some
discrete values of a vector (mean() and sd() exists, but i have not find
variation).

Thanks in advance

Adel

What exactly do you mean by "variation"? As I understand it, this term
is a broad term for all kinds of different "spread measures" (like 
quantile range or standard deviation). Do you mean the Coefficient of 
Variation? If you found out how to compute the mean and the std.dev., it 
is straightforward to calculate it.....
