sample.moments: Sample moments

Description

Computes raw moments, central moments, and standardised coefficients (CV, skewness, kurtosis) from a numeric sample.

Usage

sample.moments(
  x,
  na.rm = FALSE,
  raw = TRUE,
  central = TRUE,
  coef = TRUE,
  order = 1:4
)

Value

a named list with zero or more of:

m
