Written in C++, this function should always run faster than
for numeric vectors/matrices. For integer objects,
run even faster.
Numeric vector or matrix.

# In general, range_n is much faster than range. x <- rnorm(1000) all.equal(range(x), range_n(x)) microbenchmark(range(x), range_n(x), times = 100) # For integer vectors, range_i should be even faster. x <- rpois(1000, lambda = 5) all.equal(range(x), range_i(x)) microbenchmark(range(x), range_n(x), range_i(x), times = 100)
