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

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. _________________________________________________________________ ues clics pour retrouver tout ce qui vous intéresse au même endroit.
