Description Usage Arguments Value Examples

Best() takes a vector .x and a binary predicate function .f and returns the result of .f reduced over .x.

1	Best(.x, .f)

`.x`	A vector.
`.f`	A binary predicate function.

The best value in that vector, as determined by the binary predicate function.

# Simulate the behavior of max with numerics
Best(1:10, function(x, y) return(x > y))
# Simulate the behavior of min with numerics
Best(1:10, function(x, y) return(x < y))
# This comparison function prefers values that begin with l
Best(letters, function(x, y) return(x[1] == "l"))
