mean_i: Mean of Integer Values

In dvmisc: Faster Computation of Common Statistics and Miscellaneous Functions

Description

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

Usage

mean_i(x)

Arguments

x	Integer vector or matrix.

Value

Numeric value.

Examples

# For integer objects, mean_i is typically much faster than mean.
x <- rpois(100, lambda = 5)
mean(x) == mean_i(x)
benchmark(mean(x), mean_i(x), replications = 10000)
