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.
P.S. E-mailed CCs of posted replies appreciated.
