[R] Applying function to multiple input vectors

[Ronnen Levinson]

   Hi.
   Say I have a function f with two inputs, x and y

     f <- function(x,y) {something}

   that I wish to evaluate with two input vectors of length N

     X <- c(x1, x2, ..., xN)
     Y <- c(y1, y2, ..., yN)

   to  obtain  the  length-N  output  vector  c( f(x1,y1), f(x2,y2), ...,
   f(xN,yN) ).
   Is there a method analogous to sapply() for this operation?
   Yours truly,
   Ronnen.
