[R] variation

[Jannis]

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.....
