Fast summary statistics (C backend)

Thin R wrappers over the rmoriebricklayer compiled core – the same kernels that sibling packages reach through LinkingTo: rmoriebricklayer. NA/NaN values propagate (there is no na.rm); call stats::na.omit() first if you need NA handling.

Usage

core_mean(x)

core_var(x)

core_cor(x, y)

Arguments

x, y

Numeric vectors (coerced with as.numeric()).

Value

core_mean(), core_var() and core_cor() return a length-1 numeric. core_var() uses the n - 1 (sample) denominator, matching stats::var().

Examples

core_mean(1:10)
#> [1] 5.5
core_var(c(2, 4, 4, 4, 5, 5, 7, 9))
#> [1] 4.571429
core_cor(1:10, (1:10)^2)
#> [1] 0.9745586
