mean_i: Mean of Integer Values
In dvmisc: Convenience Functions, Moving Window Statistics, and Graphics

Description Usage Arguments Value Examples

Written in C++, this function runs faster than mean for large integer vectors/matrices.

mean_i(x)

`x`	Integer vector or matrix.

Numeric value.

# For very large integer objects, sum_i is faster than sum
x <- rpois(100000, lambda = 5)
mean(x) == mean_i(x)
benchmark(mean(x), mean_i(x), replications = 1000)

# For smaller integer objects, sum_i is slower than sum 
x <- rpois(1000, lambda = 5)
mean(x) == mean_i(x)
benchmark(mean(x), mean_i(x), replications = 1000)
