[R] Gini coefficient in R

If I use the Ineq library and the Gini function in this way:


I obtain the result 0.75 instead of 1 (that is the perfect inequality).

I think Gini's formula in Ineq is based on a formula as reported here: http://mathworld.wolfram.com/GiniCoefficient.html

but in the case of perfect inequality:

x_1=.......=x_n-1 =0


these formula are equal to 1 - 1/n, not to 1.

....I don't know where I'm wrong....
