[R] how to get the position of an element in a vector ?
Hi, dear R developers, I've got a vector of monthly volatilities and i would like to get the position of the highest volatility of the vector without computing a loop. Is there a function that could give me such a result ? a-c(1,2,4,100,3) the highest value is the fourth of the vector. how can i get 4 without a loop going through the vector ? Thanks ! Benoit.
