range_i: Range (Actually Minimum and Maximum) of Integer Values

In dvmisc: Faster Computation of Common Statistics and Miscellaneous Functions

Description

Written in C++, this function should always run faster than range for integer vectors/matrices. Not valid for non-integer objects.

Usage

range_i(x)

Arguments

x	Integer vector or matrix.

Value

Integer vector.

Examples

# In general, range_i is much faster than range
x <- rpois(1000, lambda = 5) 
all.equal(range(x), range_i(x))
benchmark(range(x), range_i(x), replications = 10000)
