range_n: Range (Actually Minimum and Maximum) of Numeric Values

In dvmisc: Faster Computation of Common Statistics and Miscellaneous Functions

Description

Written in C++, this function should always run faster than range for numeric vectors/matrices. For integer objects, range_i should run even faster.

Usage

range_n(x)

Arguments

x	Numeric vector or matrix.

Value

Numeric vector.

Examples

# In general, range_n is much faster than range
x <- rnorm(1000)
all.equal(range(x), range_n(x))
benchmark(range(x), range_n(x), replications = 5000)

# For integer vectors, range_i should be even faster
x <- rpois(1000, lambda = 5) 
all.equal(range(x), range_i(x))
benchmark(range(x), range_n(x), range_i(x), replications = 10000)
