check ?which.max(), e.g.,
x <- c(1,4,15,6,7)
which.max(x)

Subject: [R] argmax
Hello,
Is there any function that returns the argmax of a vector ?
For example I have the vector x=(1,4,15,6,7)
max(x)=15
I want a function f such that f(x)=3 because this is where max(x) is.
Thank your very much.
P.S. : I know it is a basic question but I have not figured it out by
myself.
