[R] Evaluating f(x(2,3)) on a function f- function(a,b){a+b}

Dear list I have a function and a vector, say f - function(a,b){a+b} x - c(2,3) I want to evaluate f on x in the sense of computing f(x[1],x[2]). I would like it to be so that I can write f(x). (I know I can write a wrapper function g - function(x){f(x[1],x[2])}, but this is not really
