vectorizing a function
I'm sure I'm missing something obvious but I'm not seeing how to simply
"vectorize" a function of two or more variables.
Say I have
f <- function(x,y) if (x>0) y else -y
Now I have vectors x and y of equal length and I'd like to apply f
element-wise. I.e. conceptually
z <- f(x,y) where x, y, z are vectors of the same length
Some magic involving apply?
