What's the right approach to using Map for a function with two arguments in R?
I could get the same effect by using a function which takes 1 argument that consists of a list, and then pass in a list of lists, but I'd like to know if there's a better solution.
Just feed in the extra arguments as a vector like mapply.
Map('+', 1:5, 2:6)
You can name them if you want. If they're not long enough they're recycled out to the right length (e.g. n here)
Map(rnorm, n=1, mean=1:5, sd=1:5)
Since mapply(f, c(a,b,c,...)) = c(f(a), f(b), f(c), ...), it is unclear what those extra arguments should be. If the additional arguments are fixed (or are derived from the element itself), you can use an anonymous function: mapply(function(x) g(1, true, x, 42), c(a,b,c,...)).
