As far as I know there is no such function (i could be wrong here!). The
reason for that might be that it is so straightforward to calculate it
as the ratio of sd() and mean()....for similar reasons there is most
probably no function for the variance (and only one for std.dev)....I
would think that the easiest solution for you is to create the function
(~3 lines of code) yourself!

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
Yes, that what I mean. But I looked for ready function :)

compute the mean and the std.dev., it is straightforward to calculate
it.....

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
